Execution Mechanism
After vote allocations are determined, Autopilot handles on-chain execution using a batched voting system.
The design ensures efficient processing for users with one or many veAERO or veVELO positions, minimizing gas usage and handling edge cases through built-in fallback logic.
🗳️ Batched Voting
Autopilot supports multiple veAERO and veVELO locks per wallet. To reduce overhead and ensure scalability, votes are submitted in gas-optimized batches specific to each network.
Why Batching Is Required: Without batching, each veNFT would require its own transaction, leading to:
Higher gas consumption per vote
Risk of exceeding block gas limits
Increased latency for users with multiple positions
How It Works: Batch construction:
veNFTs are grouped by owner and network (Base or Optimism).
Batches are structured to remain within each chain’s gas limit — approximately 30M on Base and slightly lower on Optimism.
On-chain submission:
Each batch contains multiple
vote()calls submitted in a single transaction.This enables fast, low-cost execution during the limited voting window.
For Velodrome, batching also accounts for bridging and multichain sync latency, ensuring votes confirm safely before the cutoff.
🔁 Handling Failures
Autopilot includes internal logic to manage potential execution failures (e.g., congestion, outdated pool data, or invalid gauge reads).
Built-in Resilience:
Retry logic: NFTs that fail to vote in a batch are retried individually through fallback transactions.
Error tracking: Failed operations are emitted on-chain via
VotingCompletedandFallbackExecutedevents.Non-blocking execution: A single failed NFT does not interrupt the remaining batch.
📘 Example: If 1 out of 50 NFTs fails due to an outdated gauge on Velodrome, Autopilot completes the batch and retries the failed one in a separate transaction.
🔐 Nonce Handling
Managing multiple NFTs per wallet requires accurate nonce sequencing to prevent transaction conflicts.
Predictive Nonce Tracking:
Autopilot tracks wallet nonce states before each batch to prevent duplication or collision.
Gas-aware execution: Nonce order is dynamically adjusted if pending transactions or retries occur, maintaining smooth flow even during high activity periods.
📦 Execution at Scale
Autopilot’s execution framework is designed for scale and performance:
Supports wallets holding dozens or hundreds of veAERO or veVELO NFTs
Optimized for institutional users and DAOs managing large voting positions
Executes all votes within the final blocks of each epoch, under constrained blockspace and network limits
Whether managing one lock or hundreds, execution remains predictable, gas-efficient, and fully automated — no manual action required.
