Overview
The USDC bridge and token launchpad on Arc.
Envelope is two things behind one app: a bridge that locks USDC on Base and issues eUSD on Arc against it one for one, and a launchpad that puts a token's entire supply into a Uniswap v3 pool at launch.
How the bridge works
USDC on Base becomes eUSD on Arc, backed one for one.
Launching a token
A fixed supply of 1 billion tokens in a Uniswap v3 pool.
Integrate

Two things to know first
Bridging is not instant. Your transaction records the request, and the funds arrive on the other chain about a minute later, once the first chain has confirmed. Check the destination chain for the balance rather than your own receipt.
Arc charges gas in native USDC. Bridging in delivers native USDC directly, so a bridged wallet arrives able to pay for its own transactions.
