Build with Signal

Integration quickstart

This reference is for trading terminals, wallets and indexers, including an Axiom integration. It does not imply a completed partnership or integration.

New launches on Signal are Signal v4 pools. If you are adding Signal today, start with Signal v4 pools and come back here for the earlier launches that still trade.

This page and the pages after it cover standard generation 2 spot-reward curves on Ramses and Project X, on HyperEVM chain 999. New curve launches are not offered on the site at present; existing curve tokens keep their contracts and their markets.

Integration path

  1. Load reviewed deployments and current /api/config. Match chain, factory, quote asset and router; do not select by ticker.
  2. Discover launches through known factory events. Read the token's actual curve and pairing links at a pinned block.
  3. Read decimals, phase and terms. Use the Pair Router's quote(curve, isBuy, amount) with integer base units.
  4. Build a wallet request with the correct spender, recipient, deadline and nonzero minimum. Simulate it from the actual wallet before asking for a signature.
  5. Recheck settings and phase before submission. Reconcile the confirmed receipt, including refunds and graduation.
  6. Index the economic fill once, preserving transaction hash, log index, block number and block hash.

Try a read

Download the read-only example to read a known Curve token using a reviewed factory and router. No private key is needed, no approvals are sent and no transactions are broadcast.

sh
npm ci --ignore-scripts
npm run example -- 0x2842cf5397d36ec9273a4bf8bccbeb23aaccb08d buy 0.01

0.01 is pairing-asset units on a buy. For this WHYPE-paired example it is 0.01 WHYPE, not $0.01. A sell amount is in launched-token units. The example uses a public RPC by default and accepts a chosen RPC through an environment variable; do not commit credential-bearing URLs.

Scope boundaries

The ABI bundle covers the standard 75/25 factories, their Pair Router and token/curve/processor implementations, plus the Project X V2 venue adapter. Historical 80/20 contracts and strategy companion factories must be integrated as distinct deployments. Hybra Classic is not this Curve ABI.

Direct-pair quoting does not quote a separate native-HYPE conversion leg, check wallet allowance or simulate execution. Do not advertise a live executable fill from the read-only sample.

Continue with quote and trade, events, and errors.
