Technical & Business Comparison
AA-Enabled Swaps vs. Traditional Bridges
A detailed breakdown of how native cross-chain swaps powered by Account Abstraction (ERC-4337) outperform legacy bridging solutions across critical operational and user experience metrics.
| Comparison Factor | Traditional Bridges | AA-Enabled Swaps |
|---|---|---|
User Experience | Multi-step: Approve, Bridge, Wait, Swap | Single-step: Sign one transaction for the complete swap |
Security Model | Custodial or trusted relayers; high exploit surface | Non-custodial; funds never leave user's smart account |
Gas Cost for User | High (2-3 transactions + bridge fees) | Optimized (1 bundled transaction, gas sponsorship possible) |
Time to Finality | 5-30 minutes (multiple block confirmations) | < 2 minutes (single atomic transaction) |
Developer Overhead | High (integrate bridge SDK, manage liquidity pools) | Low (integrate with our AA swap router API) |
Supported Assets | Limited to bridge's liquidity pools | Any asset via decentralized aggregators (1inch, 0x) |
Fee Structure | Bridge fee + destination chain gas | Single swap fee; optional gas abstraction |
Implementation Timeline | 3-6 months (custom integration) | 2-4 weeks (using Chainscore's SDK) |

Frequently Asked Questions
Get clear answers on timelines, costs, and technical details for your custom AA-enabled swap development project.
From kickoff to mainnet launch, a standard deployment takes 3-6 weeks. This includes 1 week for design and architecture, 2-3 weeks for core smart contract and frontend development, 1 week for internal testing and security review, and 1 week for client testing and deployment. Complex features like cross-chain support or novel fee models can extend this timeline, which we scope and agree upon upfront.
