OneSource is a single-host aggregation of Ethereum and Base chain RPC primitives exposed as discrete skills. It targets agents that need to inspect on-chain state — contracts, transactions, blocks, ENS names — without managing their own RPC infrastructure. It does not provide token prices, balances, ABI decoding, source code, or write operations.

Capabilities

Network State

Establishes current Ethereum network context including chain ID, block height, and gas price. Used to bootstrap or pre-flight any transaction workflow.

fetch-ethereum-chain-idfetch-ethereum-block-numberfetch-ethereum-network-info

Block Data

Retrieves full block metadata, transaction hash lists, and header fields for a specific block or the current chain tip, including the pending block.

Transaction Lookup

Fetches confirmed transaction details and receipts by hash, covering sender, recipient, value, gas, execution status, and event logs.

fetch-chain-transactionfetch-chain-transaction-receipt

Account State

Returns per-address on-chain state needed before constructing or submitting a transaction, specifically the current nonce.

fetch-chain-noncefetch-onchain-nonce

ENS Resolution

Resolves ENS names to their on-chain Ethereum addresses and verifies forward/reverse resolution status via the ENS resolver contract.

Contract Classification

Determines whether an address is a smart contract, which ERC token standards it implements (ERC-20, ERC-721, ERC-1155, ERC-165), and retrieves its on-chain name and symbol.

Bytecode Retrieval

Fetches raw deployed EVM bytecode and code length for an address, enabling contract verification, decompilation, or EOA/contract distinction.

Proxy Detection

Identifies whether a contract address is a proxy, returns the proxy pattern type, and resolves the underlying implementation address.

Workflows

Transaction Pre-Flight Check

Use when an agent needs to prepare and validate all on-chain parameters before constructing and signing an Ethereum transaction.

1
fetch-ethereum-network-infoRetrieve chain ID, current block number, and gas price in one call to establish network context.
2
fetch-onchain-nonceFetch the current nonce for the sender address to ensure correct transaction sequencing.

Contract Introspection

Use when an agent needs to fully characterize an unknown contract address before interacting with it.

1
fetch-contract-metadataDetermine if the address is a contract, identify its token standard, and retrieve name and symbol.
2
detect-evm-proxy-contractCheck whether the contract is a proxy and resolve the underlying implementation address if so.
3
fetch-contract-bytecodeRetrieve raw bytecode for further analysis or verification if needed.

ENS-to-Contract Inspection

Use when an agent receives an ENS name and needs to resolve it to an address and then characterize the contract at that address.

1
fetch-ens-name-resolutionResolve the ENS name to its on-chain Ethereum address.
2
fetch-contract-metadataClassify the resolved address as a contract or EOA and identify its token standard.
3
detect-evm-proxy-contractDetermine if the resolved contract is a proxy and find its implementation address.

Transaction Confirmation Audit

Use when an agent needs to verify that a submitted transaction was mined successfully and audit its gas consumption and block placement.

1
fetch-chain-transactionRetrieve full transaction details including sender, recipient, value, and block number.
2
fetch-chain-transaction-receiptConfirm execution status, gas used, and event logs for the same transaction hash.

Block Transaction Enumeration

Use when an agent needs to enumerate and inspect transactions in the most recent confirmed block.

1
fetch-latest-blockchain-blockRetrieve the current chain tip block and its list of transaction hashes.
2
fetch-chain-transactionLook up details for individual transaction hashes extracted from the block.

Own skills.onesource.io? List it with your agent

Paste the prompt below to your coding agent. It runs a real paid test on every route, fixes what scores low, and re-auditions until they pass — the gaps below are already filled in for you.

1 of 49 route has never been scored — the audition tests it for the first time.
14 routes are scoring below 50 — likely broken, mispriced, or returning the wrong shape.
4 routes are in the 50–74 band — working, but with room to climb.
20 routes are flagged by the verifier as failing or inconclusive.

Paste this to your agent

Make my x402 API at https://skills.onesource.io discoverable on x402gle. Read the instructions at https://x402gle.com/agent.md and follow them end to end. Install the OpenDexter CLI, then run `npx @dexterai/opendexter audition https://skills.onesource.io --json`. Heads up: 1 route has never been scored and 14 routes are scoring below 50 — start there. Read the score and fixInstructions for every route, fix my OpenAPI and endpoints until each route passes, and re-audition until it does. A passing audition lists my API automatically.
