How to convert Optimism to Arbitrum
Converting OP to ARB on NEAR Mobile Swap is done in three simple steps through the NEAR Intents protocol: Deposit, Swap, and Withdraw.
Step 1 — Deposit OP from Optimism network
Go to the Deposit tab and select Optimism (OP) on its native OP chain. The widget will generate a deposit address (or QR code) — send your OP there from any wallet. Once confirmed, your OP balance appears inside the NEAR Intents chain.
Step 2 — Swap OP to ARB on NEAR Intents
Switch to the Swap tab. Both tokens are already on the NEAR Intents chain — pick OP as the source and ARB as the target. Enter the amount and confirm — swaps settle in seconds with no bridging required.
Step 3 — Withdraw ARB to Arbitrum network
Finally, go to the Withdraw tab. Select Arbitrum (ARB) from your NEAR Intents balance and choose the ARB chain as the destination. Enter your wallet address and confirm — the withdrawal usually completes in under a minute.
⚠ Important: When entering a withdrawal address, make sure it is a personal wallet you control. Some centralized exchanges do not support receiving funds from smart-contract-based deposits — sending to an exchange address may result in lost funds.
