Veyronn Documentation

Chain Package

Use Veyronn chain definitions, configuration, units, ABIs, and EIP-712 schemas.

The @veyronn/chain workspace package keeps browser, BFF, indexer, keeper, tests, and scripts on the same protocol types.

Chain definitions

import { robinhoodChain, robinhoodChainTestnet } from "@veyronn/chain";

console.log(robinhoodChain.id);        // 4663
console.log(robinhoodChainTestnet.id); // 46630

The definitions include native ETH, official RPC defaults, and Blockscout explorers.

Runtime configuration

loadVeyronnConfig reads chain ID, RPC, contract addresses, deployment block, confirmations, and service settings from environment variables. It rejects unsupported chain IDs.

Typed data

The package exports canonical EIP-712 schemas for:

signed oracle reports
delegated intent messages

Always use the shared domain and message builders. Hand-constructed type definitions can produce signatures that appear valid in the wallet but fail contract or keeper verification.

Units

Protocol USD values use six decimals. Convert user input to integer micro-USD at boundaries and keep bigint internally. Avoid JavaScript floating-point arithmetic for transaction values.

ABIs

Generated JSON ABIs cover:

VeyronnProtocol
CollateralVault
SignedOracleRouter
mainnet OracleRouter
StrategyNFT
ConditionalEvaluator
testnet collateral and feed helpers

Regenerate ABIs after contract interface changes:

npm --workspace @veyronn/chain run generate:abis

Then rebuild all consumers and rerun contract, service, and web checks.
