Advanced Order Types and Execution
Limit and Stop Orders
MetaMask Delta Exchange supports limit, market, and stop orders, giving users precise control over entry and exit points. Orders can be edited or canceled while resting in the book, subject to availability and protocol rules.
Partial Fills and Post-Only Mode
Partial fills allow traders to execute against available liquidity without needing the full size at once. Post-only mode helps liquidity providers add depth and avoid taker fees when conditions are met.
Security and Asset custody
Non-Custodial Design
Users retain custody of their funds using MetaMask’s secure enclave and key management. Signing occurs locally, and trades are submitted only after user confirmation through the familiar MetaMask prompt.
On-Chain Settlement
Each swap settles on-chain or via layer-2 state channels depending on the network, with transparent transaction hashes available in the portfolio history. MetaMask does not hold user funds, and withdrawals follow the user’s explicit instructions.
Supported Tokens and Networks
The platform focuses on highly liquid tokens and curated pairs to reduce slippage and improve price discovery. Multi-chain support enables fast moves between Ethereum mainnet and popular L2s without leaving the wallet interface.
Dynamic routing selects the best sources, including automated market makers and institutional liquidity, while displaying estimated fees and expected arrival time for each route.
