Building GraphQL APIs on Ethereum
Level up your open finance game 5x a week. Subscribe to the Bankless program below. The Graph is a protocol for organizing blockchain data. Until recently The Graph has been fairly centralized. You can use it to build and publish open APIs, call subgraphs, and make data easily accessible for the crypto ecosystem.
DeFi protocols like Aave, Synthetix, and Uniswap currently leverage subgraphs from The Graph to power their interfaces.
APIs or "Application Programming Interfaces" are a set of instructions and standards through which interactions can happen between an application or web tool and applications that use its assets. At the end of the day, APIs allow developers to save time and reduce the amount of code created. There are vast amounts of raw data on Ethereum.
This data needs to be stored in a format that can be easily and efficiently queried—this is essential for fast loading web applications and good user experience. The Graph makes querying blockchain data reliable, secure and fast as a subgraph sorts and indexes specific data for the applications that use them.
The Graph is middleware for the Web3 stack. It allows applications to efficiently query blockchain data without relying on a centralized service provider and helps make fully decentralized applications a reality. With open public networks like Ethereum and the proliferation of DeFi, The Graph is building the foundation for all crypto applications that utilizes open data. The Uniswap subgraph is used here to query data directly from Uniswap smart contracts.
The Graph indexes the useful data sets allowing the creation of infographics such as visualized forms of Uniswap data on token pairs. All of the above participants can earn income from the network proportional to the amount of work performed and GRT staked.
Consumers require GRT to pay fees to indexers. The token aligns incentives and economic security within the network between all participants, rewarding healthy participation and punishing malicious behavior. Indexers are the node operators of the protocol.
They run the physical infrastructure required to process indexing and query services. Indexers must Stake GRT in order to earn query fees and inflationary rewards.
Indexers are compensated the most out of all other participants and can create a marketplace with their own pricing models and strategies. Curators stake GRT against subgraphs. Their vote create market signals on what subgraphs are valuable, which helps indexers allocate resources. As a result, curators earn a portion of indexer rewards and fees. Delegators stake GRT to indexers in order to earn a portion of rewards and fees. This allows passive token holders to participate in network security and sybil resistance.
Consumers of subgraphs—mainly Ethereum DeFi applications—need to access data on The Graph without having to do the work to compute and store that data. They leverage The Graph to securely and efficiently query data. Fees can be handled by Gateways in progress or by a query engine this can be an extension or embedded into the dApp, abstracted from normal users which makes decisions on which indexers to use from the fee market.
Consumers query the Indexers and paying for metered usage. This creates a supply and demand model which sustains the protocol. For now, only a few subgraphs have migrated from the hosted service to mainnet. Query fees are still low, but expected to grow as more subgraphs migrate to mainnet. Delegators use their GRT to delegate to existing indexers and earn a portion of that Indexer's rewards and fees.
Delegators are also subject to a 0. For example, an Indexer that shares a smaller percentage of rewards to Delegators but has less Delegated Stake than a competitor who shares more rewards might be more profitable to stake to as you could be entitled to a larger proportion of delegator rewards shared with less delegators. Once you have selected an Indexer, click on the icon to the far right of the row. Click on delegate and another window will appear.
Click on submit transaction. This will open your Metamask. Give it a few minutes to confirm on-chain and that's it! You can manage and find an overview of your Delegations if you click on your address in the upper right corner of the Network Beta dApp. Curators can stake GRT on any number of subgraphs of their choosing. These tokens can be used to redeem GRT from the curve at any point in the future by burning the share tokens.
In short, Curators are essentially locking up GRT in exchange for a Curator Reward, which is paid as a share of future query fees.
This will make it drastically easier for users to participate as Curators! A bonding curve creates a continuous token model where the purchase and sale of tokens is handled by a smart contract, without a party in the middle facilitating the trades.
The tokens are traded for coins of a parent currency that are held in reserve by the smart contract. Above, the Y axis represents the price of the token shares while the X axis is the amount of shares minted by the curve. When staking as a curator, you are depositing funds into a reserve for a specific subgraph. Curators will aim to deposit into subgraphs that are, or suspected, to be in demand with many queries, thus attracting liquidity. The earlier you stake on a subgraph, the greater the share of query fees you can earn for the given amount of GRT deposited as reserves are added to the contract more stakers.
As a result, you can withdraw your stake with more GRT than initially deposited after some time. Bonding your GRT to a subgraph early does not guarantee future revenue!
There has to be demand for the subgraph in order for curation to be profitable. That said, depositing into a contract with more liquidity can be seen as less risky with lower reward, as it's a market signal that the subgraph is already in demand! In the future, a Curation Tax will be implemented which will make certain types of economic attacks unprofitable and disincentivizes poor decision making that could harm the integrity of the network. Curators also earn fewer query fees if they choose to curate on a low-quality subgraph, since there will be fewer queries to process or fewer indexers to process those queries.
Ultimately, this encourages longer term commitments and higher quality curated marketplace. Anyone can create a subgraph, so there will be duplicates or ones that do more or less the same thing.
Some may have bugs, work incorrectly or be optimized for certain data sets over generalized. With real economic risk and reward , Curators should carefully consider subgraphs selection. Evaluation metrics such as below can help:. The first place to look is the subgraph page on the explorer, you should find a Github link to find the code repository to dig into the code.
You can also test querying data, in some cases a default query example is provided or you may need to compose yourself. The community of Curators Discord has growing resources and collaboration on this, where you can find Guides on what to look for in subgraph evaluation. ROI: High, Indexers earn the bulk of the Network revenue, competitive market of Indexers with individual pricing models. Indexers are node operators in The Graph Network. In return for their services, indexers earn query fees and rewards from new token issuance for their services.
Note that this is very compute intensive. Additionally, an indexer agent programmatically monitors their resource usage, sets prices, and decides which subgraphs to index. Node operators can decide their own pricing models and strategies to gain a competitive edge in the marketplace. Query fees are collected in a rebate pool, where they can later be claimed according to a rebate reward function.
Indexers are incentivized to stake proportional to the amount of query fees they earn, this signals economic security behind the queries they serve while consumers can see the capacity of that indexer for their needs. Indexers also have a delegation capacity, which is a ratio of Indexers owned stake, and can be slashed if Indexers are malicious and serve incorrect data to applications or index incorrectly, this also allows passive token holders to participate without risk of slashing.
Delegators have less of a trust relationship with Indexers and will look at Indexers on chain activities such as uptime or fees generated in order to encourage decentralization. The Graph is a crucial piece of middleware for the broader Ethereum ecosystem. It allows DeFi applications to index and query data in a universal standard, allowing for better tools and applications to be built. Though The Graph is still rolling out on mainnet, there are already ways to earn yield as a delegator, curator, or indexer.

Graph-Indexer-Service don't work with http (no https) --ethereum endpoint - Rust graph-node
Several of our engineers, myself included, have spent a substantial portion of the past year working on building low level Ethereum infrastructure at BitGo. Our first attempt in at building a highly indexed database of the Ethereum blockchain used EthereumJ to run the EVM in the JVM and thus parse every transaction and contract that ever occurred on the network. This ended up being a poor decision. We experienced multiple crashes, subpar documentation, and not so great developer support from the small number of EthereumJ experts. We lost count of how many times our EthereumJ client got stuck or corrupted and we had to delete the entire chainstate and re-sync from scratch. We never managed to stabilize our EthereumJ indexer to the point that we were confident it was ready for production use.

Homepage Repository npm TypeScript Download. An overview of Scalar , a microtransaction framework for query fees, can be found here. Run the following at the root of this repository to install dependencies and build the packages:. The easiest way to run the indexer service agent is by using Docker. Docker images can either be pulled via. This starts the indexer agent and serves the so-called indexer management API on the host at port
Blockdaemon is proud to announce full-node support for The Graph , a decentralized query protocol for indexing and caching data from blockchains and storage networks, by participating as an Indexer in the network. The Graph is democratizing access to data in open, permissionless networks, fueling the growth of decentralized applications dApps. Traditionally, data has existed in silos, managed and curated by large, centralized entities who build and maintain the most popular modern applications. Today, dApps are putting users in control of their data.
Contributor: What does it mean to use an open API? For example, Uniswap uses a subgraph and that data is open to any developer to use in their application. Thus, we see wallets like Rainbow wallet that have built a subgraph that pulls from Uniswaps subgraph. The most efficient way to query search data from the blockchain is via a subgraph. Prior to The Graph, developers had to spin up centralized servers and databases in house in order to index and query blockchain data.
