ABI Registry

Fetch ABIs at Runtime

Always fetch ABIs from Bridge - they stay current with contract redeployments:

async function getABI(contractName: string) {
  const res = await fetch(
    `https://bridge.presschain.io/abis/${contractName}`
  );
  if (!res.ok) throw new Error(`ABI not found: ${contractName}`);
  const { abi } = await res.json();
  return abi;
}

// Batch fetch for a full integration setup
const [registryABI, acceptanceABI, bondABI, membershipABI] = await Promise.all([
  getABI("ArticleRegistry"),
  getABI("CapsuleAcceptance"),
  getABI("BondManager"),
  getABI("OutletMembership"),
]);

In production, cache fetched ABIs during your build step - don’t fetch on every page load. ABIs only change on contract redeployments, which are announced via status.presschain.io.

Integration Priority Order

Implement contracts in this order. Higher priority = called more frequently in typical outlet and journalist workflows.

ArticleRegistry - Submit and query Capsules

Every publishing integration starts here.

GET https://bridge.presschain.io/abis/ArticleRegistry

Key methods:

function submitCapsule(
  string calldata outletSlug,
  string calldata articleSlug,
  string calldata metadataURI,
  bytes32 contentHash,
  uint256 policyId
) external returns (uint256 capsuleId)

function finalizeCapsule(uint256 capsuleId) external
function capsuleCount() view returns (uint256)

CapsuleAcceptance - Voting engine

Cast votes, query vote state, trigger finalization.

GET https://bridge.presschain.io/abis/CapsuleAcceptance

Key methods:

function vote(uint256 capsuleId, bool support) external

function getVoteState(uint256 capsuleId) view returns (
  uint256 yesVotes,
  uint256 noVotes,
  uint256 weightedYes,
  uint256 weightedNo,
  uint256 participation,
  bool finalized,
  bool accepted
)

function isVotingOpen(uint256 capsuleId) view returns (bool)

OutletMembership - Outlet onboarding and bond state

Required for any outlet-level operation.

GET https://bridge.presschain.io/abis/OutletMembership

Key methods:

function isOutletActive(string calldata slug) view returns (bool)

function getOutletBond(string calldata slug) view returns (
  uint256 bondedAmount,
  uint256 lockedUntil,
  bool active
)

OutletRoleShop - Role purchases at outlet level

GET https://bridge.presschain.io/abis/OutletRoleShop

BondManager - Protocol-level bond management

GET https://bridge.presschain.io/abis/BondManager

Confirmed live methods:

function minimumBondByRole(uint8 role) view returns (uint256)
function isRoleActive(address wallet, uint8 role) view returns (bool)

function getRoleBond(address wallet, uint8 role) view returns (
  uint8 role,
  uint8 state,
  uint256 bondedAmount,
  uint256 minimumRequired,
  uint256 activatedAt,
  uint256 updatedAt
)

function dissolutionFeeBps() view returns (uint16)
function depositBond(uint8 role) payable
function dissolveBond(uint8 role)

function transfer(address to, uint256 amount) returns (bool)
function approve(address spender, uint256 amount) returns (bool)
function allowance(address owner, address spender) view returns (uint256)
function transferFrom(address from, address to, uint256 amount) returns (bool)

Full Integration Setup Pattern

import { JsonRpcProvider, Contract } from "ethers";

const BRIDGE = "https://bridge.presschain.io";
const RPC    = "https://rpc.presschain.io";

const ADDRESSES = {
  ArticleRegistry:   "0x121885Cd339BF495cbC63e0f49e16c7CB2A1C62a",

  BondManager:       "0x4b39edF3fA0e7DBAFFA45FDCBbE08B6681D1076b",
  tPRESS:            "0xe1cC4228c29cb4e1Ff4B836f445b7ee3FBb04e32",
} as const;

async function initContracts() {
  const provider = new JsonRpcProvider(RPC);

  // Fetch all ABIs in parallel
  const abis = await Promise.all(
    Object.keys(ADDRESSES).map(async (name) => {
      const res = await fetch(`${BRIDGE}/abis/${name}`);
      const { abi } = await res.json();
      return [name, abi] as const;
    })
  );

  const abiMap = Object.fromEntries(abis);

  return {
    articleRegistry: new Contract(ADDRESSES.ArticleRegistry,   abiMap.ArticleRegistry,   provider),
    acceptance:      new Contract(ADDRESSES.CapsuleAcceptance, abiMap.CapsuleAcceptance, provider),
    membership:      new Contract(ADDRESSES.OutletMembership,  abiMap.OutletMembership,  provider),
    bondManager:     new Contract(ADDRESSES.BondManager,       abiMap.BondManager,       provider),
    tpress:          new Contract(ADDRESSES.tPRESS,            abiMap.tPRESS,            provider),
  };
}

// Usage
const contracts = await initContracts();

// Read capsule count
const count = await contracts.articleRegistry.capsuleCount();
console.log("Total capsules:", count.toString());

// Check voting is open
const open = await contracts.acceptance.isVotingOpen(247n);
console.log("Voting open:", open);

// Check bond
const bonded = await contracts.bondManager.isRoleActive("0xADDRESS", 2);
console.log("Reporter bond active:", bonded);
