In Brief:
- The Fort Canning upgrade is slated to reach the Enjin Relaychain on Nov. 9, followed by the Enjin Matrixchain on Nov. 16. Each mainnet rollout hinges on its governance referendum passing.
- New features include NFT loans that conclude automatically, tokens that expire on a set schedule, mint limits open to public verification and token attributes that become permanent once set.
- The upgrade also introduces OpenGov to the Matrixchain and lifts the governance proposal deposit from 0.025 ENJ to 1,000 ENJ per track.
Enjin is preparing to activate Fort Canning on the Enjin Relaychain on Nov. 9, an update the company describes as the largest upgrade in Enjin Blockchain history. A week after that, the Enjin Matrixchain is due to receive its own upgrade. In both cases, the governance referenda must pass first.
Enjin laid out the feature set in a post on X. Among the highlights were “NFT loans that end on their own,” “Tokens that expire on schedule” and “Mint limits anyone can check.” The list also featured “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

Schedule and block targets
The Relaychain will shift to runtime 1.8.0 at block #18,059,100 on Nov. 9 as part of Fort Canning. The Matrixchain follows on Nov. 16, moving to runtime 1.4.1 with block #12,331,000 as its target. Both are expected to take place at roughly 16:00 UTC.
According to Enjin, these timings are estimates derived from current block times. The Relaychain block is fixed by its referendum, whereas the Matrixchain block is only a target.
The upgrade is already running on the Canary test networks. The Canary Relaychain received it on Sept. 28, and the Canary Matrixchain on Sept. 29.
Lending with automatic return
With token lending, owners can set up NFT loans for a fixed term. Once the term ends, the token returns to the lender automatically. While the loan is active, the borrower may use the token but cannot transfer it, burn it or list it on any other venue.
Lending is unavailable for tokens minted before the upgrade unless the collection owner grants permission. Enjin intends the feature for rentals and trials rather than collateralized lending.
Changes are coming to the marketplace as well. It will add support for sENJ and the Degens collection, and ENJ auction bids will be placed into escrow the moment they are submitted.
Expiry, mint caps and locked attributes
Fort Canning introduces tokens that expire according to a set schedule, as well as mint limits that are publicly verifiable. Enjin’s documentation already describes supply modes that restrict how many tokens a collection owner is able to mint.
The upgrade further adds immutable token attributes. At present, owners can use the mutateToken call to modify fields including a token’s behavior, listing flag, infusion permission, on-chain name and attributes.
OpenGov on the Matrixchain
OpenGov is coming to the Matrixchain, complete with 15 referendum tracks and conviction voting. With conviction voting, holders who lock their ENJ for longer gain greater voting weight.
Submitting a proposal will now require a deposit of 1,000 ENJ per track, up from 0.025 ENJ. The upgrade also establishes minimum support thresholds tied to the total ENJ supply of 2.02 billion, a figure that includes ENJ held on the Matrixchain.
Validator and XCM changes
Relaychain validators that lose parachain disputes will be subject to slashing. The GRANDPA authority limit is also being raised from 32 to 100, making room for larger validator sets.
In addition, Fort Canning will “add new XCM APIs that enable wallets to simulate transactions and estimate associated costs before submitting them.” Moving ENJ between the Relaychain and the Matrixchain will continue to rely on teleport.
Background
The previous upgrade, Bugis, brought the Relaychain to runtime 1.5.0 in February 2025 and halved the Matrixchain’s block time from 12 seconds to six. Fort Canning is its successor.
The principle behind Fort Canning’s lending feature is straightforward: once the term expires, the NFT returns to its owner with no action required from anyone.
