In Brief:
- Enjin has scheduled its Fort Canning upgrade for the Enjin Relaychain on Nov. 9 and the Enjin Matrixchain on Nov. 16. Each mainnet upgrade depends on its governance referendum passing.
- The release adds NFT loans that end automatically, tokens that expire on a schedule, publicly checkable mint limits and token attributes that can’t be changed after they’re set.
- It also brings OpenGov to the Matrixchain and raises the deposit for a governance proposal from 0.025 ENJ to 1,000 ENJ per track.
Enjin has scheduled Fort Canning, which it calls the largest upgrade in Enjin Blockchain history, to go live on the Enjin Relaychain on Nov. 9. The Enjin Matrixchain upgrade is planned for one week later. Both depend on their governance referenda passing.
The company announced the features on X. “NFT loans that end on their own,” “Tokens that expire on schedule” and “Mint limits anyone can check” were on the list. So were “Item details locked for good” and “ENJ holders govern the Matrixchain.”
Fort Canning, the largest upgrade in @enjin Blockchain history, brings:
➼ NFT loans that end on their own
➼ Tokens that expire on schedule
➼ Mint limits anyone can check
➼ Item details locked for good
➼ ENJ holders govern the Matrixchain
Live Nov 9 on the Relaychain and
Schedule and block targets
On Nov. 9, Fort Canning moves the Relaychain to runtime 1.8.0 at block #18,059,100. On Nov. 16, the Matrixchain moves to runtime 1.4.1, with a target of block #12,331,000. Both upgrades are planned for about 16:00 UTC.
Enjin said the times are estimates based on current block times. The Relaychain block is set by its referendum. The Matrixchain block is a target.
The Canary test networks already have the upgrade. The Canary Relaychain was upgraded Sept. 28 and the Canary Matrixchain Sept. 29.
Lending with automatic return
Token lending creates fixed-term NFT loans. When a loan ends, the token goes back to the lender automatically. Borrowers can use a token during the loan, but they can’t transfer it, burn it or list it anywhere else.
Tokens minted before the upgrade can’t be lent unless the collection owner allows it. The feature is meant for rentals and trials, not collateralized lending.
The marketplace is also changing. It will support sENJ and the Degens collection. ENJ auction bids will go into escrow as soon as they’re placed.
Expiry, mint caps and locked attributes
Fort Canning adds tokens that expire on a set schedule, along with mint limits that anyone can check. Enjin’s documentation already includes supply modes that cap how many tokens a collection owner can mint.
It also adds token attributes that can’t be changed. Right now, the mutateToken call lets owners edit fields such as a token’s behavior, listing flag, infusion permission, on-chain name and attributes.
OpenGov on the Matrixchain
The Matrixchain is adopting OpenGov with 15 referendum tracks and conviction voting. Under conviction voting, ENJ that holders lock for longer periods carries more voting weight.
The deposit to submit a proposal goes from 0.025 ENJ to 1,000 ENJ per track. The upgrade also sets minimum support thresholds based on the total ENJ supply of 2.02 billion. That figure counts ENJ held on the Matrixchain.
Validator and XCM changes
On the Relaychain, validators who lose parachain disputes will face slashing. The GRANDPA authority limit goes from 32 to 100, which allows larger validator sets.
Fort Canning will also “add new XCM APIs that enable wallets to simulate transactions and estimate associated costs before submitting them.” ENJ transfers between the Relaychain and the Matrixchain will still use teleport.
Background
Fort Canning comes after Bugis, which moved the Relaychain to runtime 1.5.0 in February 2025. Bugis cut the Matrixchain’s block time from 12 seconds to six.
Fort Canning’s lending feature follows a simple rule: when the term runs out, the NFT goes back to its owner without anyone having to act.
