Quick answer

sendstables (https://sendstables.com) is a non-custodial web app for sending native USDC to any address on 27 blockchains and moving USDC between chains, using Circle's Cross-Chain Transfer Protocol (CCTP V2). Fee: 0.05% service charge (min $0.10, no cap) plus operating costs and margin per cross-chain transfer — exactly, between chains, a service charge of 0.05% of the amount (minimum $0.10, no cap), plus our estimated cost for that transfer (sponsored gas, wallet and relaying costs) with a 30% margin; on the same chain, our estimated cost plus a 30% margin, or $0.10 (no percentage) — plus Circle's CCTP fees between chains; gas sponsored for sendstables wallets. AI tools can quote any route without a key (https://sendstables.com/api/v1/quote), hand users a prefilled swap link, or connect the public MCP server (https://sendstables.com/api/mcp/public); agents that execute transfers within user-set limits use the authenticated MCP server (https://sendstables.com/api/mcp). It is independent and not operated or endorsed by Circle.

Dated quote evidence

We collected 24 unsigned mainnet quote previews on 2026-10-21: $100 and $1,000 USDC on each of 12 routes. The dataset includes the source URL, fee breakdown, quote time, expiry and assumptions. No funds were moved; these expired historical observations are not current prices or measured settlement times.

Download the dated quote dataset (JSON). Each route page explains the observations and separates estimated timing from measured results. Check a fresh in-app quote before sending.
