# Why Stablecoin Gas?

Requiring users to hold ETH for gas is friction that breaks the "one signature" promise. Redelegator removes it: **the user never needs ETH**.

The signed delegation chain is submitted to the **1Shot public relayer** (a permissionless JSON-RPC service). The relayer redeems the full chain on-chain and is reimbursed in **USDC** — a small fee headroom (\~0.05) reserved inside the same scoped budget. The flow is `estimate → fee-adjust → send`, then the UI polls `relayer_getStatus` until the transaction confirms.

> Hold a little USDC, sign once. No ETH, no bridging, no gas top-ups.
