All cases
A cross-chain messaging protocol.
Arcane developed a protocol that lets smart contracts exchange messages across independent blockchains. The work covered the on-chain entry points, message verification and delivery logic that allow an action on one network to trigger application logic on another.
From a transaction on one chain to an action on another.
Give applications a common messaging interface
An application submits a payload to an endpoint on its source chain. The protocol packages that payload with its sender, destination and channel sequence, then routes it towards the receiving contract. Developers integrate a send-and-receive interface while keeping the meaning of each message in their own application logic.
Make verification part of the protocol
Before a destination contract can act, the protocol must establish that the message corresponds to an event on the source chain. We worked across that verification path and the checks that bind a payload to its origin and intended receiver. Message sequencing and replay checks keep each channel’s delivery state coherent as traffic moves between networks.
Carry the message through to execution
Sending and receiving happen in separate transactions, under different gas budgets and network conditions. The protocol tracks a message through delivery and destination handling, including failure states and recovery paths. This is the engineering that lets the receiving application handle a cross-chain instruction while distinguishing transmission, verification and successful execution.
Build infrastructure other products can use
The result is a programmable communication layer for applications that operate across networks. Asset bridges, cross-chain contract calls and coordinated financial workflows can build on this foundation. Arcane’s role was to develop the protocol machinery beneath those experiences, from message construction and verification to destination handling.
