Arbitrum RWA fund hits $374M

Arbitrum’s tokenized-asset buildout is being led, for now, by short-duration government debt. Data circulated on May 21 by ecosystem accounts showed Spiko’s EU T-bill fund at more than $374 million on Arbitrum, making it one of the clearest examples of real-world assets finding product-market fit on an Ethereum layer-2. The same batch of updates also pointed to two adjacent moves elsewhere in the layer-2 market: Kraken-backed Ink adding cheaper oracle access through Chainlink Scale, and Starknet pushing private Bitcoin transfers through strkBTC. Taken together, the developments show where the current race is moving — not toward one feature, but toward a stack of settlement, data and privacy tools institutions might actually use. ### Why does a tokenized T-bill fund matter more than another DeFi launch? Spiko and the Arbitrum Foundation announced in January 2025 that Spiko had deployed its U.S. and E.U. T-Bills Money Market Funds on Arbitrum One, with $159 million in assets under management at the time. The funds are UCITS-compliant vehicles with tokenized shares, and Spiko said they were designed to serve as onchain cash-management products and collateral. Arbitrum later said on X that Spiko’s EU T-bill fund had grown 5.5x in one year to more than $374 million, while real-world assets on the Arbitrum platform expanded 3.5x across multiple asset classes. That matters because tokenized money-market funds are one of the few crypto products already tied to an underlying asset class institutions understand: short-dated sovereign paper.

Nina Rong, head of partnerships at the Arbitrum Foundation, said in the January 2025 announcement that Spiko’s deployment showed how Arbitrum could support “institutional-grade RWA adoption” and enable “compliant, regulated financial products.” Spiko said at the time that the network would give it an onchain venue for collateral and treasury management. (twiscan.com) The pitch is less about crypto-native speculation than about operating rails. A tokenized fund issuer needs wallets, transfers, settlement finality and integration with other onchain applications. Arbitrum’s role in that stack is to offer Ethereum-linked infrastructure with lower transaction costs than mainnet, while keeping compatibility with the broader Ethereum ecosystem. That description is an inference from Arbitrum’s stated positioning and Spiko’s use case. (prnewswire.com) ### Why are Chainlink and Ink part of the same conversation? Ink said on May 19 that it had joined Chainlink Scale and upgraded to Chainlink Data Feeds as its oracle infrastructure. Third-party coverage describing the announcement said the arrangement was meant to give developers on Ink lower-cost access to price data used by DeFi applications. (prnewswire.com) Chainlink’s own newsroom shows similar Scale integrations for other chains this year, including Unichain in March. That places Ink’s move in a broader pattern: layer-2 networks are trying to reduce one of the fixed costs of launching financial applications, which is dependable external data. ### Where does Starknet’s private Bitcoin fit in? Starknet introduced strkBTC in February as a wrapped asset redeemable for native bitcoin, with optional shielding for private balances and transactions. (cryptowisser.com) The project said the aim was to let bitcoin holders use DeFi without exposing all balances and transfers on a public ledger. (chain.link) Starknet’s blog index shows strkBTC went live on May 12, with launch guides tied to wallets, bridging and DeFi use on Starknet applications. The network also said last month that Starknet v0.14.2 had added the infrastructure for private transactions and for STRK20 assets including strkBTC. ### So what should readers watch next? May 12, May 19 and May 21 are the useful dates in this sequence. (starknet.io) Starknet has already launched strkBTC, Ink has already attached itself to Chainlink Scale, and Arbitrum ecosystem accounts are now highlighting the size of Spiko’s fund and broader RWA growth. The next concrete checkpoints are likely to come from issuer disclosures, chain dashboards and official network announcements showing whether more tokenized funds, collateral products or institution-facing apps follow onto the same rails.
