+# Solana Paymaster: Pay Gas in USDT
+
+We just shipped our first product outside the EVM. The Solana Paymaster lets accounts that hold zero SOL send SPL token transfers, with the network fee paid in USDT inside the same transaction.
+
+<!-- truncate -->
+
+## The same problem, one more chain
+
+We've spent years on this problem for EVM chains: users hold stablecoins, not gas tokens. On Solana it's the same story with different names. An account holding USDT but no SOL can't move its own money, and asking a stablecoin user to go buy SOL first is where most wallets lose them.
+
+Our EVM answer is the ERC-4337 token paymaster. Our Solana answer is a paymaster built on [Kora](https://solana.com/docs/tools/kora), Solana Foundation's open fee payer standard. The paymaster cosigns each transaction as its fee payer, fronts the SOL for fees and rent, and collects the equivalent in USDT within the same transaction. Because it speaks Kora's JSON-RPC protocol, any Kora client works with it. No proprietary SDK required. 
+
+## One config object, one call  
+
+The paymaster works with any Kora client. If you're using [Wallet Development Kit (WDK)](https://docs.wallet.tether.io) by Tether, the whole flow is one config object and one call:
+
+```ts
+import { WalletAccountSolanaGasless } from '@tetherto/wdk-wallet-solana-gasless'
+
+const wallet = new WalletManagerSolanaGasless(seedPhrase, {
+    provider: rpcUrl,
+    paymasterUrl,                                // your Candide Solana Paymaster endpoint
+    paymasterAddress,
+    paymasterToken: { address: USDT_MINT },
+    transferMaxFee: 1_000000n,                   // abort if the fee exceeds 1 USDT
+})
+
+const account = await wallet.getAccount(0)
+await account.transfer({ token: USDT_MINT, recipient, amount: 100000n })
+```
+

+- Get your Solana Paymaster endpoint at [dashboard.candide.dev](https://dashboard.candide.dev)
+
+## Where this is going
+
+Mainnet USDT is the only fee token today. Sponsored transactions, where you cover fees for your users the way InstaGas does on EVM chains, are next.
+
+If you're building a stablecoin product on Solana, try it and tell us what breaks.

+The Solana Paymaster covers transaction fees and collects them in USDT, so accounts never need to hold SOL. It runs [Kora](https://solana.com/docs/tools/kora), the Solana Foundation's open fee-payer standard. See the [guide](/wallet/guides/pay-gas-in-usdt-solana/).

-## Core Features
-
-*Smart accounts are programmable contracts, unlocking capabilities impossible with traditional EOAs.*
-
-### Gas Abstraction
-- Gasless transactions: [Sponsor user fees](/wallet/guides/send-gasless-tx/) with flexible rules and policies
-- ERC-20 gas payments: Let users [pay gas in any token](/wallet/guides/pay-gas-in-erc20/) (USDC, DAI, etc.). No ETH required
+## Look It Up
 
-### Modern Authentication
-- Passkey integration: [Onchain WebAuthn](/wallet/plugins/passkeys/) support for biometric login. No seed phrases
-- Social login: [Email and OAuth](/wallet/guides/authentication/#social--email) integration
+Reference material for when you're mid-integration and need an answer, not a tutorial.
 
-### Chain Abstraction
-- Sign once, execute on every chain: one signature authorizes [UserOperations across every chain](/wallet/guides/chain-abstraction-overview/) you target
-- Same account everywhere: one address on every EVM network where Safe is deployed
-
-### Advanced Transactions
-- Batch operations: [Execute multiple transactions](/wallet/guides/getting-started/) atomically
-- Spending controls: [Set limits and policies](/wallet/plugins/allowance) for subscriptions and recurring payments
-
-### Security
-- Account recovery: [Social Recovery](/wallet/plugins/recovery-with-guardians) or [traditional](/wallet/recovery/auth-api/) recovery options
-- Multi-signature: A single account controlled with [multiple signatures](/wallet/guides/multisig/)
-
-## Onboarding & Deposits
-
-Users don't always arrive on the chain your app runs on. [Forwarding Address](/forwarding-address/overview/) gives each user one deposit address that accepts funds from any supported chain and routes them automatically to the destination wallet. Built for onramps, exchange withdrawals, and payment flows.
