Stablecoin

Aave DAO has approved an Aave Request for Comment (ARFC) snapshot vote to kick off community discussion on deploying Aave V4 to Ethereum mainnet, with a rollout expected this year. The vote ran four days and closed with 100% support, starting a non-binding phase before any onchain Aave Improvement Proposal and deployment. V4 introduces a modular Hub-and-Spoke design and deeper integration of the GHO stablecoin, as the protocol navigates contributor changes including planned exits by BGD Labs and Aave Chan Initiative.

Resolv paused its protocol after a private key compromise let an attacker mint about $80M in uncollateralized USR, sparking a sharp depeg. The team said roughly 9M USR linked to the attacker has been burned, and the only confirmed loss so far is about $0.5M from redemptions processed before the pause. USR later traded near $0.19, down over 56% in 24 hours, while Resolv reported holding around $141M in assets as it prepares a redemption plan for pre-incident holders.

Fidelity Investments submitted a letter on March 20, 2026 urging the SEC to create a framework that allows broker-dealers to offer, custody, and trade crypto assets on Alternative Trading Systems. The firm also called for clearer standards for tokenized securities, updated reporting rules for DeFi, and guidance on using distributed ledger technology for recordkeeping without being labeled a "clearing agency."

As of March 23, 2026, an analysis of 5,000 XRP Ledger blocks found that payments accounted for 53.20% of over 1 million sampled transactions. OfferCreate activity followed with about 371,895 transactions (34.2%), while NFTokenBurn ranked third at about 65,369. In the same block set, Ripple USD (RLUSD) led stablecoin-related transfers with 92,699, ahead of ARK at about 10,281.

On 23 March 2026, major international banks advanced pilot programs for tokenized deposits across multiple jurisdictions as they look to bring bank money onto blockchain rails. The initiatives emphasize that tokenized deposits retain bank-style safeguards such as AML compliance, capital rules, and deposit insurance, while Europe works to connect distributed ledgers with existing payment systems by the second half of 2026.

The House Financial Services Committee will meet Wednesday at 10:00 AM ET to examine how securities could be moved onto blockchain-based rails and whether current securities laws impede tokenized assets. Lawmakers are set to question witnesses from Nasdaq, DTCC, SIFMA, and the Blockchain Association while reviewing two draft bills tied to SEC-CFTC coordination and blockchain record-keeping for regulated firms.

Bernstein said Circle (CRCL) and Coinbase (COIN) remain the most direct ways to gain exposure to stablecoin growth, pointing to their shared USDC ecosystem. The firm argued that agentic machine payments could become an additional upside lever, though activity is still small, with Coinbase's x402 processing about $25 million over the past 30 days and Stripe's MPP seeing $5,000 in its first week.

ERC20 stablecoin usage expanded sharply, with active addresses rising from about 85,000 in March 2025 to nearly 600,000 in March 2026, pointing to more sustained on-chain participation. Data in the report also show a preference shift in supply growth, with USDC up $4.5 billion year-to-date while USDT supply fell by roughly $2 billion. Exchange reserves were reported at $65.37 billion, down 0.72% in 24 hours, alongside net outflows of over $485 million.

US lawmakers and White House officials agreed in principle on Friday to settle rules for yield on stablecoins, aiming to unblock broader crypto legislation in the Senate Banking Committee. The framework would still prohibit issuers from paying interest directly, while allowing platforms to offer regulated rewards tied to reserve-backed instruments, with caps linked to Treasury rates under discussion. The compromise is expected to be put into formal text before an April committee vote.

Banks are ramping up tests of tokenized deposits to move commercial bank money onto blockchain-based payment and settlement rails. The RWA.io report says these bank-issued liabilities are developing alongside stablecoins and CBDCs within an emerging onchain cash stack, with multiple pilots underway in Europe. It also notes the ECB's parallel work on digital euro infrastructure, including Pontes, which is scheduled to launch in Q3 2026.
