# Gas Sponsorship

Your users transact, you cover the gas — sponsored transactions on six EVM chains, Solana and TRON.

Token holders without native coins are stuck balances and support tickets. Every product that
issues wallets meets the same wall: a user holds your token, holds no ETH, SOL or TRX, and cannot
move their own balance. Sponsorship removes the wall — any address in your vault can pay the
network fee for any sender.

## One funded sponsor, zero stuck users

- **Designate a fee payer** — any address in the vault sponsors any sender, vault-wide rather than
  per account. Top it up and monitor it like any treasury address; its balance is your natural
  spend cap.
- **No wrapper contracts, no relayers** — EVM sponsorship uses EIP-7702 directly, so there is no
  paymaster contract to deploy and no relayer holding funds in transit.
- **Chain by chain** — Ethereum, Base, BSC, Arbitrum, Polygon and Optimism via EIP-7702; Solana
  through its native fee payer, with both keys signing one transaction; TRON through sponsored
  TRC-20 transfers via token approvals.

## Sponsorship is a payment path, not a bypass

Sponsored transfers clear the same signing policies as everything else. The fee payer signs its
part in the same MPC ceremony, under the same governance, and the fee payer must differ from the
sender — enforced, not advised. Sponsorship works with batch payouts on the same endpoint family.

## FAQ

**Which plans include it?**
Business and Enterprise.

**Does the user need any native coin at all?**
No. The fee comes from the sponsor address you fund, not from the user's empty wallet, which is
the whole point of the feature.
