Gensyn RPC API

Yes. Gensyn provides an EVM-compatible blockchain where people and AI agents can interact with smart contracts. Its ecosystem includes Delphi, an information-market platform where humans and agents can create and trade markets on-chain. Broader work also includes verifiable AI and auditable model training. Gensyn also publishes agent tooling, including the TypeScript Delphi SDK and Agentic Trading Toolkit.

GetBlock runs managed Gensyn nodes and serves them over JSON-RPC (HTTPS) and WebSocket. Gensyn's own documentation recommends a dedicated provider or self-hosted node for production instead of the public endpoint, and GetBlock covers that. Endpoints expose the full eth_*, net_*, and web3_* method set plus the debug_* trace namespace. GetBlock endpoints cover the Gensyn chain only; AXL, REE, and Delphi's market API are separate Gensyn components.

Any EVM-compatible wallet can connect to Gensyn by adding the network with Chain ID 685689 and ETH as the native currency, including MetaMask and ERC-4337 smart accounts. Standard Ethereum libraries such as ethers.js, viem, and web3.py work without modification. Solidity tooling like Foundry and Hardhat can deploy and test contracts against a Gensyn endpoint the same way as on Ethereum. Gensyn's TypeScript Delphi SDK also accepts any RPC endpoint, so agents built on it can run against GetBlock directly.

Gensyn RPC nodes return account balances, nonces, contract bytecode, and storage values, along with full block and transaction data. Receipts include status, gas used, event logs, and OP Stack L1 fee fields. On Gensyn, that includes events from Delphi market contracts, such as trades and settlements, plus $AI and stablecoin transfers.

Create a Gensyn endpoint in the GetBlock dashboard to receive an access token, then send JSON-RPC requests to https://shared.us-east-1.getblock.io/<ACCESS-TOKEN>/. A WebSocket endpoint is available for subscriptions. In wallets and SDKs, configure Chain ID 685689 (0xa7679) and ETH as the native currency. Delphi SDK users can replace the default public endpoint by setting GENSYN_RPC_URL to the GetBlock endpoint.

Gensyn supports the standard Ethereum JSON-RPC methods. The most frequently used are eth_call, eth_getLogs, eth_sendRawTransaction for submitting signed transactions (forwarded to the sequencer), eth_getTransactionReceipt for confirmations, and eth_feeHistory for fee estimation. For debugging, debug_traceTransaction and debug_traceCall return step-by-step execution traces.

Yes. GetBlock's Gensyn endpoints support WebSocket connections with eth_subscribe for newHeads, logs, newPendingTransactions, and syncing events. With 2-second blocks, newHeads and logs subscriptions deliver chain updates close to real time. Gensyn's transaction pool is private to the sequencer, so newPendingTransactions carries less signal than on chains with a public mempool.

The Gensyn mainnet Chain ID is 685689 (0xa7679 in hex), and the network ID returned by net_version uses the same value. Gensyn Testnet uses Chain ID 685685 and settles to Ethereum Sepolia.
