@sinjoh/abis

Generated, viem-typed ABIs for the Sinjoh contracts on Robinhood Chain. Use this package when you need the canonical callable surface without importing the higher-level SDK.

Install

npm install @sinjoh/abis viem

Use an ABI

import { sinjohFeeRouterAbi } from "@sinjoh/abis";
import type { Address, PublicClient } from "viem";

export function readRouterSubject(client: PublicClient, router: Address) {
  return client.readContract({
    address: router,
    abi: sinjohFeeRouterAbi,
    functionName: "subject"
  });
}

Every ABI export is a TypeScript as const value, so viem infers function names, arguments, and return types. Contract names use lower camel case followed by Abi, such as sinjohRaffleRewardsAbi and sinjohPonsV2AdapterAbi. The governed protocol upgrade is exported in the same package, including feeRouterV2Abi, stakingEngineAbi, sinjohStakingEngineAbi, yieldBasketAbi, dynamicFundingBandsAbi, and sinjohGovernorAbi, plus sinjohLaunchStakingEngineAbi, addressGovernanceControllerAbi, governanceControllerFactoryAbi, governedAbi, immutableGovernanceControllerAbi, and stakedVotesAdapterAbi. These upgrade exports are source/ABI artifacts only except for the independently deployed SinjohLaunchStakingEngine described below.

sinjohAirdropDistributorAbi remains the default standard airdrop surface and does not require staking. sinjohStakingEngineAbi is the separate optional surface for staking-driven, claim-based distributions. Its zero-stake epochs roll pending rewards into a later eligible window. stakingEngineAbi exposes simple raw-balance staking: one token equals one reward unit and one non-delegated vote, stake adds to the balance, and unstake immediately removes any available portion. There are no tiers, locks, multipliers, or cooldowns. Timestamp checkpoints preserve completed epoch and governance snapshots after a later unstake. yieldBasketAbi exposes token-specific reward routes and the governed, fully-paused adapter write-off/recovery lifecycle, plus governance-only recovery for non-deposit tokens received outside a verified harvest. feeRouterV2Abi exposes per-route escrow balances, permissionless retry, and governed recovery so one paused or reverting destination does not freeze unrelated fee routes.

Project V2 exports include projectLauncherV2Abi, projectLaunchValidatorV2Abi, projectRegistryV2Abi, projectRouterV2Abi, projectTreasuryVaultV2Abi, projectAirdropV2Abi, projectStakingPoolV2Abi, projectLiquidVotesWrapperV2Abi, and the remaining governed module ABIs. The liquid-votes wrapper provides one-for-one deposits and withdrawals for an ordinary external Project token while preserving governance checkpoints. projectRouterV2Abi is the complete routed-asset surface: one route may execute ordered direct sends, swaps, buyback-and-burn, Treasury funding, Airdrop funding, Raffle funding, liquidity, and project-sink actions. Generated ABI values remain the source of truth for action tuple shapes and callable signatures.

sinjohLaunchStakingEngineAbi is the production platform surface for new launches that opt into staking-required airdrops. It is a shared multi-token contract: every launched token is its own staking subject, one staked token is one reward unit, and unstaking is immediate. Reward accounts are isolated by fee router, subject, and payout asset. The reviewed Robinhood Chain deployment is available as mainnet.contracts.launchStakingEngine from @sinjoh/deployments. It is unrelated to the older single-token $INJOH deployment.

Provenance

abiSourceCommit records the repository commit used to generate the package. abiContractCounts records the number of contracts harvested from each Foundry package. Generation includes only compilation targets under each package's src/ directory; tests, scripts, mocks, copied interfaces, and vendored libraries are excluded.

Do not edit generated files. From the repository's sinjoh-sdk directory, build the Foundry packages and run npm run generate. CI fails when committed ABIs drift from build output.

See the SDK workspace documentation for the package map and release status.
