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. Any address in your vault can pay network fees for any sender — EIP-7702 sponsored transactions on EVM, the native fee-payer on Solana, token-approval transfers on TRON.

A user holding your token and no native coin is a support ticket
Token holders without ETH, SOL or TRX cannot move their own balance. Every product that issues wallets meets this wall: stuck balances, confused users, and a support queue explaining gas. Sponsorship removes the wall — any address in your vault can pay the network fee for any sender.
- Stuck balances stop being your problemThe fee comes from a sponsor address you fund, not from the user's empty wallet.
- No wrapper contracts, no relayersEVM sponsorship uses EIP-7702 directly, so there is no paymaster contract to deploy and no relayer holding funds in transit.
- Your spend cap is a balanceThe sponsor is an address you top up and monitor like any treasury address. Its balance is the ceiling.
One funded sponsor, zero stuck users
Designate a fee payer
Any address in the vault can sponsor any sender — vault-wide, not per-account. Keep it topped up with the native coin and monitor it like any treasury address; its balance is your natural spend cap.
- ✓Ethereum, Base, BSC, Arbitrum, Polygon, Optimism — via EIP-7702
- ✓Solana — native fee payer, both keys signing one transaction
- ✓TRON — sponsored TRC-20 transfers via token approvals
Policy still rules
Sponsored transfers clear the same signing policies as everything else. Sponsorship is a payment path, not a bypass — the fee payer signs its part in the same MPC ceremony, under the same governance.
- ✓Fee payer must differ from the sender — enforced
- ✓Works with batch payouts on the same endpoint family
- ✓Business and Enterprise plans
Sponsorship, chain by chain
The mechanism is different on each family — the integration is not.
Where sponsorship changes the product
A new user can transact on their first minute, before they have ever bought a native coin.
Merchants withdraw their stablecoin balance without you shipping them gas first.
Item and reward transfers that feel free to the player, funded from one address you control.
The boundaries worth knowing
You pay the fee instead of the user. The win is UX and support load, plus the fee mechanics we optimise underneath.
Six EVM chains, Solana and TRON have one today. On the rest, the sender pays.
If the sponsor address empties, sponsored transfers fail like any underfunded transaction. Monitor it as you would a hot wallet.
Fee-payer support is built for the current v2 vault type. Legacy vaults need a reshare first.
