What is the current OP to SEI rate?

Most OP to SEI swaps finish in 5–30 minutes, depending on OP deposit confirmations and SEI network load. Each route shows its own ETA before you commit.

No. CoinSwap is non-custodial: your OP goes straight to the executing route and your SEI is sent to the address you provide. We never hold your funds.
