eUSD to USDC migration
eUSD-paired pools migrate to USDC one for one, automatically.
Tokens can launch paired in eUSD today. Once Circle's own USDC bridge to Arc is live, every eUSD-paired pool converts to USDC one for one, with no action needed from the creator or from holders.
What migration does
The migration withdraws the pool's liquidity, exchanges the eUSD for USDC one for one, and recreates the same pool: same price, same token amount, same range, now denominated in USDC. Creator fees continue, in USDC. Nothing about the value of your position changes.
Tokens paired in USDC never need migration.
If you index pools
The pairToken on the factory changes when a pool migrates. Read it rather than assuming it
stays constant. See Indexing and pricing.
