EIP-7702 lets EOAs delegate to a smart contract — batching, gas sponsorship, and session keys without changing address. Architecture and builder's checklist.
Account Abstraction
Best Account Abstraction Providers in 2026
Compare the top account abstraction (ERC-4337) providers in 2026. Features, pricing, and scope from Openfort to Alchemy.
What EIP-8141 Means for Developers
EIP-8141 brings native account abstraction to Ethereum. But it's not the only proposal — Base is backing EIP-8130, and Paradigm proposed Tempo. Here's an honest take on who's right, what the tradeoffs are, and how to position yourself for what's coming.
How to Set Up Gasless Transactions
A step-by-step guide to implementing gasless transactions on Ethereum and Solana using Openfort's paymaster infrastructure. Sponsor gas fees for users and AI agents with code examples, policy configuration, and real-world best practices.
Gasless Transactions on Ethereum
Openfort lets your app sponsor gas on Ethereum and EVM chains, so users transact without holding ETH — and can even pay fees in stablecoins like USDC.
Technical Dive: Gas Sponsorship via Paymasters
How paymasters enable gas sponsorship: Verifying and ERC-20 modes, the on-chain validation lifecycle, paymasterData encoding, and security trade-offs.
Gasless Transactions on Solana
Sponsor gas on Solana with Openfort so users transact without holding SOL — and let them pay fees in stablecoins like USDC, USDT, or USDG. With code examples.
