Fees for bridging USDC with Xebra
The bridge always shows exactly what the recipient will get before you sign, read live from the contracts and from Circle. This page explains how that figure is made. Figures are as set on the contracts on 2026-10-15; they can only change after a public 48-hour wait.
From Stellar
Xebra's fee is 0.1% of the amount, at least 0.30 USDC. Circle's delivery fee is paid out of Xebra's fee, not added on top: if Circle's fee is ever the larger of the two, you pay Circle's fee and Xebra keeps nothing.
| You send | Fee | Recipient gets |
|---|---|---|
| 10 USDC | 0.30 USDC | 9.70 USDC |
| 50 USDC | 0.30 USDC | 49.70 USDC |
| 100 USDC | 0.30 USDC | 99.70 USDC |
The only other cost is the Stellar network fee, a fraction of a cent in XLM. Each transfer is 1 to 100 USDC.
From Arc
Transfers out of Arc go through Xebra's contract on Arc with the same rule: 0.1% of the amount, at least 0.30 USDC, with Circle's delivery fee paid out of it. Arc charges gas in USDC, a fraction of a cent per transaction; keep a few cents in the wallet.
Circle's delivery fee
Circle's Forwarding Service charges for submitting the mint on the destination and paying the gas there. It differs by chain and moves with gas prices; the bridge reads Circle's live quote. Xebra refuses to sign a delivery fee above these limits, and never one above a tenth of the amount:
| Route | Most Circle may charge |
|---|---|
| Stellar → Solana | 0.25 USDC (0.45 when Circle opens the account) |
| Stellar → Arc | 0.10 USDC |
| Stellar → Base | 0.25 USDC |
| Arc → Avalanche | 0.50 USDC |
| Arc → OP Mainnet | 0.50 USDC |
| Arc → Arbitrum | 0.50 USDC |
| Arc → Base | 0.50 USDC |
| Arc → Polygon | 0.50 USDC |
| Arc → Unichain | 0.50 USDC |
| Arc → Codex | 0.50 USDC |
| Arc → Sonic | 0.50 USDC |
| Arc → World Chain | 0.50 USDC |
| Arc → Monad | 0.50 USDC |
| Arc → Sei | 0.50 USDC |
| Arc → XDC | 0.50 USDC |
| Arc → HyperEVM | 0.50 USDC |
| Arc → Ink | 0.50 USDC |
| Arc → Solana | 0.50 USDC (1 when Circle opens the account) |
Small transfers
Because Circle's fee may be at most a tenth of what is burned, the smallest transfer depends on the route and on Circle's fee that day. From Stellar it is about 1 USDC to Arc, about 2 USDC to an existing Solana account and more to a new one. The bridge tells you if an amount is too small before you sign.
