How It Works in 2027

Ethereum core roadmap enhancements for account abstraction allow smart contract accounts and native protocol enclaves to delegate gas reimbursement to ERC-4337 Paymasters. Users never have to bridge, swap, or hold native ETH just to execute basic smart contract interactions.

Paymaster Liquidity & Markup

Paymasters lock native ETH with the EntryPoint contract and simultaneously accept stablecoin transfers from users. To hedge against micro-volatility between the block proposal and settlement, Paymasters charge a nominal spread (0.2% - 1.0%).

Impact on ETH Staking & Supply

Even though users pay in stablecoins, the underlying Ethereum validators and builders still receive and burn native ETH via EIP-1559 base fee burning. The Paymaster executes the continuous background conversion, preserving Ethereum's monetary burn dynamics.
