Bridge USDT from Solana to Arbitrum

Open the transfer interface at usdt0.to/transfer and connect Phantom, Solflare, or another Solana wallet. Pick Solana as the origin and Arbitrum as the destination, enter the amount, then approve the transaction in your wallet. The transfer usually completes in about 26s, depending on Solana finality.

Moving USDT between Solana and Arbitrum goes through the Legacy Mesh, which charges 0.03% (3 bps) of the amount, paid in USDT. You pay network gas on Solana and the LayerZero messaging fee that carries the transfer, both quoted in the interface before you confirm.

USDT0 on Arbitrum is the USDT0 representation of USDT within the USDT0 Network. It keeps one unified USDT across supported chains instead of a separate bridged version with isolated liquidity, and stays backed 1:1 by USDT held in reserve. On Arbitrum it works as the USDT asset available through USDT0.

Transfers are secured by LayerZero, the interoperability protocol behind USDT0, and by the USDT0 Attestation System, which verifies every transfer through independent attestation before it finalizes. Each message needs sign-off from the Core Attestation Set, a 3-of-3 signer group of USDT0, LayerZero, and Canary, so no single verifier can approve a transfer on its own. On this pair the funds move through the Legacy Mesh, a non-custodial hub-and-spoke design routed through the Arbitrum hub and backed by real assets on both sides, with no wrapped tokens and no external bridges.
