COTI Testnet

COTI Testnet is the private execution side of Privacy on Demand. Host-chain dApps (for example on Avalanche Fuji) send encrypted work through the cross-chain Inbox; COTI runs the private computation and returns encrypted results.

Note: Addresses below reflect the current PoD test deployment. They may change after contract redeploys. Confirm against your SDK release or environment before production use.

Protocol helpers (COTI Testnet)

These are not PoD-specific, but most PoD clients need them for account onboarding and chain tooling:

How this network fits PoD

Piece	Role on COTI Testnet
Inbox	Receives mined requests from host chains and routes callbacks back
MPC executor	Target address host dApps pass to configureCoti(..., COTI_TESTNET_CHAIN_ID)
Price oracle	Converts fee budgets between host gas units and COTI

Typical pairing for this section:

• Host: Avalanche Fuji C-Chain · Execution: COTI Testnet (see the private Adder tutorial)

SDK constants

In @coti-io/pod-sdk and @coti-io/coti-contracts:

Constant	Value
Chain ID	7082400
Inbox	0x3b8B70819f27e0438cBcE7f31894f799da52648F (COTI_TESTNET_DEFAULT_INBOX_ADDRESS)

Confirm the MPC executor against your deployed release — presets in PodNetworkConstants can lag a redeploy; wire the address from the table above (or your env) in configureCoti.
