suiami

One name, every chain. Zero bridges.

Resolve a single SuiNS or ENS name to native BTC, ETH, and SOL addresses — each one signed by an IKA threshold MPC dWallet, encrypted by Seal, queryable from anywhere.

npm i suiami

import { readByName, readByEns } from 'suiami/roster';

const brando = await readByName('brando.sui');
// { name, sui_address, chains: { btc, eth, sol, … }, dwallet_caps, updated_ms }

const alice = await readByEns('alice.waap.eth');
// same shape — ENS subnames resolve through the same roster

That's it. No bridge contracts, no RPC endpoints to configure, no wallet handshake. Any JS runtime, any edge worker, any browser.

Why this exists

ENS resolves Ethereum addresses for Ethereum-aware apps. username.cb.id is custodial. Lens and Farcaster are social graphs that terminate at a profile, not a UTXO. Sui zkLogin onboards users to one chain.

SUIAMI is the plumbing. Given a name, hand me the right address on the right chain — BTC, ETH, SOL, Sui — where the name owner actually holds the key. The key isn't in a bridge contract. It isn't on our server. It's a threshold share across the IKA validator set plus the owner's local share — neither half can sign alone.

Who it's for

• Sui dApp builders who want ENS reach without writing a bridge. Your *.waap.eth users already work in MetaMask, Coinbase Wallet, Brave, Rainbow.
• Fintech / onramp engineers who need alice.waap.eth to resolve to ETH when sending ETH and BTC when sending BTC. One CCIP-read call per send. PayPal resolves ENS across SLIP-44 coins today — so do we.
• Privacy-minded users who want one handle across chains without publishing every address. Your roster lives as Seal-encrypted Walrus blobs; only you can decrypt, and only the record for the chain being queried needs to reveal.

Every chain address comes from an IKA dWallet DKG — the private key was never reconstructed at the user, never existed on our server. Signing requires 2f+1 IKA validators to cooperate with the user's local share. Reads are permissionless; decrypts of Seal-encrypted cross-chain records are owner-only via the v3 seal_approve_roster_reader_v3 policy.

API

// Lookups (public — no wallet required)
readByName(name, opts?)         // "brando.sui"
readByAddress(address, opts?)   // "0x3ca0…222b"
readByChain(chain, addr, opts?) // "btc", "bc1q…" — reverse lookup
readByEns(ensName, opts?)       // "alice.waap.eth"

// Hashes
nameHash(bareName)              // keccak256(bare)
ensHash(ensName)                // keccak256(full)

// PTB builders (for client-side tx construction)
buildSetIdentityArgs(name, chains, caps?)        // SuiNS-gated write
buildSetEnsIdentityArgs(ensName, ethSig?)        // ENS bind (owner-locked)

// Proof tokens (off-chain identity attestation)
buildMessage(name, addr, nftId, chains?, balanceUsd?)
createProof(message, bytes, signature)
parseProof(token)
extractName(message)

// Constants
ROSTER_PACKAGE         // original id — use for PTB targets + type tags
ROSTER_PACKAGE_LATEST  // latest published-at — Seal v3 policy calls
ROSTER_OBJECT          // shared Roster object id

// Server-side verification
import { verify } from 'suiami/verify';
const result = await verify(token, { maxAgeMs: 300_000 });
// checks sig freshness, fetches on-chain SuiNS NFT ownership, validates domain match.
// Node / Deno / Cloudflare Workers / Bun — works everywhere.

Trust layer

• IKA 2PC-MPC: every chain address derives from a DKG round across the IKA validator set. No single party — including the user — ever reconstructs the full key. Signing requires threshold cooperation.
• Seal policy (on-chain Move): suiami::seal_roster::seal_approve_roster_reader_v3 — gate-keeps decrypt of the Walrus-stored cross-chain squids. Caller's Sui address must match the record's owner.
• Seal key servers (mainnet, 2-of-3): Overclock, Studio Mirai, H2O Nodes. No centralized decrypt bottleneck.
• Walrus: cross-chain records live as Seal-encrypted blobs on Walrus. Blobs are currently pinned to the Walrus testnet publisher/aggregator — mainnet migration tracked upstream.
• Mainnet package: original-id 0x2c1d63b3…e1052fa · v5 published-at 0xea0b9485…d4f202.
• UpgradeCap holder: plankton.sui. Changes gate-kept by a known Sui address, not a relayer or admin key.

Unaudited. Use at your own risk. Third-party review is on the roadmap. In the meantime: read the Move, read the TypeScript, read the tests in the .SKI monorepo.
