How crossr works

crossr is a multichain token launchpad. A launch is one manifest: name, ticker, metadata, creator settings and a list of legs, one per chain. The manifest hash is the launch id and the CREATE3 salt, so the token has the same address on every chain.

Explore: one card per launch, all its legs as chain badges, curve progress across the bottom. A gold chip marks launches with at least one graduated leg.

Constant-product curve per leg, 1% fee, snipe tax in the first seconds.

The curve sells out into a locked full-range Uniswap v4 pool at the same price.

One signature launches every leg through LayerZero; the bridge burns and mints.

Same curve in SOL or an xStock, same launch id, Token-2022 mints.

1% per trade: 70% to the creator, 30% to the platform, 80% of which buys CROSSR.

Trust assumptions

Ownerless tokens, a capped owner role, and no audit yet.

Developer docs

Build on crossr

Everything here is what the web app itself does. Contracts are plain Solidity you can call from any client, the shared package gives you typed ABIs, manifest hashing and the curve math, and the indexer exposes a small REST API. Source: github.com/andrewkyrz/crossr-contracts.

Launchpad, LaunchToken, relay, bridge, locker, hook and escrow.

The struct that is hashed into the launch id, and how to host metadata.

createLaunch, relay specs and the exact msg.value to send.

Trading a curve

Quote, buy, sell, track curve state, then move to the v4 pool.

Anchor IDL, PDAs, create_leg with a creator binding, SPL quotes.

quoteSend, send, endpoint ids and the paired BridgeSent / BridgeReceived events.

balanceOf and claim on FeeEscrow, collecting LP fees from the locker.

Chains, manifest hashing, curve math, LayerZero options, ABIs.

Launches, tokens, trades, holders, candles, portfolio and prices.
