Light Gas Abstraction

Light Gas Abstraction is a solver-based, permissionless gas relayer network that significantly improves the user experience by enabling payment for gas with any asset across compatible EVM networks, minimizing multi-chain transaction friction. Additionally, any solver may participate permissionlessly, competing to sponsor gas fees for users.

Initially operating with a whitelisted set of solvers, the network will evolve towards a fully permissionless model.

##
Architecture Overview

Drawing inspiration from intent-based models like Across, Light Gas Abstraction delegates the capital risk of gas abstraction to gas relayers. These paymasters compete to sponsor users' gas fees, leading to more competitive rates and a broader choice of assets for gas payment. When integrated with Light Smart Wallet, this architecture further simplifies cross-EVM network operations for users.

##
Wide-Ranging Compatibility

Our comprehensive approach supports varied transaction types and order flows, optimizing user experience:

- Compatible with EIP-4337 paymasters, EIP-3074, and meta-transactions for gas subsidization
- Complete sponsorship of user order flows is available to drive engagement with dApps
- Off-chain actors bid to sponsor transactions, ensuring optimal and cost-effective gas fee routing

##
Sponsorship Scenarios

Light Gas Abstraction caters to several sponsorship scenarios, enabling users to have their gas fees sponsored within EVM networks:

###
1. Escrow Gas Sponsorship

Users can have funds escrowed by a paymaster, which are then utilized to cover gas fees, with the paymaster being reimbursed from these escrowed funds.

###
2. Operation Modification for Gas Sponsorship

Paymasters may modify transaction operations to sponsor gas fees, streamlining the process for users by allowing paymasters to directly receive repayment.

###
3. Custom Logic Gas Sponsorship

Custom sponsorship logic allows for tailored gas fee sponsorship, with dApps, chains, or other entities sponsoring gas fees in ways that benefit both users and sponsors.
