bridgelisted

Cross-chain bridging via the ChainGPT plugin. Across Protocol v3 — the highest-volume intent-based bridge by quote count. 10 EVM mainnets supported. Custody-free: plugin builds the unsigned depositV3 transaction; user signs externally on the origin chain, then a relayer fills on destination ~seconds later. Triggers: bridge, cross-chain, move from base to ethereum, send to arbitrum, L2 to L1, bridge USDC, optimism to polygon.

# ChainGPT Bridge Skill You move funds between EVM mainnets via Across Protocol v3. Intent-based — once the deposit lands on the origin chain, a relayer (Across calls them "fillers") provides the destination liquidity within seconds. Fees: capital + relay gas + LP, all returned in the quote. ## Tools | Tool | Purpose | |---|---| | `chaingpt_bridge_quote` | Fees + estimated fill time + SpokePool addresses | | `chaingpt_bridge_build_deposit_tx` | Unsigned `depositV3` tx (refuses mainnet w/o ack) | | `chaingpt_bridge_status` | Track a deposit by origin-chain tx hash | ## The mandatory pipeline ```text chaingpt_bridge_quote │ (surface fees + fill time to user) ▼ chaingpt_dex_approve_tx token=<inputToken> spender=<spokePoolAddress from quote> acknowledgeMainnet=true │ (skip if inputToken is native — ETH/MATIC/etc.) [user signs the approval] │ ▼ chaingpt_bridge_build_deposit_tx (requires acknowledgeMainnet=true) [user signs the deposit on the ORIGIN chain] │ (~seconds later) ▼ chaingpt_bridge_status depositTxHash=<hash> │ (returns destination fill tx hash once relayer fills) ▼ chaingpt_onchain_tx hash=<destination fill hash> chain=<destination> ``` ## Supported networks Ethereum · Base · Arbitrum · Optimism · Polygon · BSC · Avalanche · Blast · Linea · Scroll. Any pair of these can be bridged. ## Key behavior - **Fee math**: input − relay_fee − lp_fee = output. The quote returns the exact `outputAmount` nee
