Comparison of Execution Models
Published 6/8/2026, 4:45:17 AM
Bebop and Aori offer guaranteed rates by replacing the public, slippage-prone Automated Market Maker (AMM) model with private, intent-centric architectures. Bebop utilizes a Request-for-Quote (RFQ) system that locks in prices with professional market makers off-chain, while Aori employs a high-frequency off-chain order book that ensures atomic "fill-or-revert" execution.
Comparison of Execution Models
| Feature | Bebop (RFQ Model) | Aori (Order Book Model) |
|---|---|---|
| Core Mechanism | Request-for-Quote (RFQ) | Off-chain Central Limit Order Book (CLOB) |
| Execution Rate | Guaranteed: The quoted price is the final price; gas is included. | Deterministic: Orders fill at the signed price or revert entirely. |
| MEV Protection | Private Quoting: Negotiated off-chain, bypassing the public mempool. | Intent-Based: Users sign desired outcomes, shielding details from searchers. |
| Settlement | Direct on-chain settlement with a market maker. | Modular settlement (e.g., LayerZero) with atomic logic. |
| Latency/Speed | Quote-based (seconds) | Ultra-low latency (5–15ms matching). |
How They Solve Aggregator Issues
Bebop: RFQ and Zero Slippage
Bebop mitigates the uncertainty of traditional aggregators by connecting users directly to private liquidity providers. In a standard aggregator, a trade might fail or suffer slippage if the underlying AMM price moves before the transaction is mined. Bebop's RFQ model ensures that the price seen by the user is the price executed, as market makers bear the risk of price fluctuations between the quote and on-chain inclusion [Source: https://medium.com/bebop-dex/wtf-is-mev-protection-42628f83e407]. This architecture also enables "one-to-many" or "many-to-one" token swaps in a single transaction without multiple hops.
Aori: Atomic Intent Settlement
Aori addresses execution risk through an intent-based framework where users sign a specific desired outcome (e.g., "receive at least X tokens"). An off-chain sequencer matches these orders in milliseconds [Source: https://l2ivresearch.substack.com/p/aori]. The guarantee is enforced by atomic settlement: if the destination amount falls below the user's signed minimum due to market shifts, the entire transaction reverts, preventing partial fills or "bridge limbo" [Source: https://eco.com/support/en/articles/12783022-what-is-aori-intent-settlement-2026].
MEV Protection
Both protocols protect users from "sandwich attacks" and front-running by moving the trade discovery process out of the public mempool:
- Bebop: Transactions are only broadcast once the rate is locked, neutralizing the ability for bots to front-run the trade [Source: https://medium.com/bebop-dex/wtf-is-mev-protection-42628f83e407].
- Aori: By using signature-based gasless orders and off-chain matching, Aori prevents searchers from identifying profitable opportunities before they are settled [Source: https://chain.link/article/mev-protection-mechanisms]. Market makers can also update quotes frequently without leaving an on-chain footprint [Note: not independently confirmed].
In summary, Bebop and Aori provide guaranteed rates by shifting the risk of execution from the user to professional solvers and market makers, using off-chain coordination to ensure that on-chain settlement is either perfect or non-existent.
