The OCC gave Ripple final approval for Ripple National Trust Bank, 10 months after the conditional nod in December 2025. A federal bank, just not one that takes deposits.

As a trust bank, RNTB takes no deposits and makes no loans. It will manage the segregated reserves behind RLUSD, act as collateral trustee for holders and offer digital asset custody to enterprises. RLUSD (about $2.6B market cap) is still issued by Ripple's NYDFS-regulated trust company, with BNY as primary reserve custodian. The new charter adds federal supervision on top of the state license.

Next, RNTB starts operations while the US rolls out the GENIUS Act stablecoin rules. Ripple counts more than 85 licenses worldwide.

Jump Crypto, the trading firm behind Solana validator client Firedancer, has changed its bug bounty terms: every report now requires burning 1 SOL (about $100). The fee is nonrefundable even for invalid, out-of-scope or duplicate submissions, and reports without a burn are not eligible for rewards.

A $1M audit competition from April 9 to May 9 drew 809 reports from 162 researchers, but only 127 unique security findings.

Nearly half of valid submissions were duplicates, the review backlog peaked at 299 open reports, and Jump believes AI agents helped find or write nearly every submission. The new platform also caps each main report section at 3,000 characters.

Rewards are rising alongside the fee: eligible findings pay double through Nov. 20, or triple for bugs in Alpenglow, Solana's new voting system, with critical Alpenglow flaws eligible for up to $300,000.

South Korea's largest exchange has expanded support for Nillion, the privacy-focused blind computation network, with a new KRW market listing for NIL. The token was already available on Upbit's BTC market, where it last closed at 0.0000011 BTC (117.6 KRW).

KRW trading is scheduled to open on October 27 at 16:40 KST (07:40 UTC). Deposits and withdrawals are supported only via the Ethereum network, and Upbit warns that transfers over any other network will not be credited.

For the first 5 minutes, buy orders are blocked and sell orders more than 10% below the previous close are rejected; only limit orders are accepted for about 2 hours.

KRW pairs typically bring the bulk of Upbit's retail volume, so a won market gives NIL direct access to the exchange's largest pool of Korean traders. Upbit notes that the start time may be delayed if sufficient liquidity is not secured after deposits open.

The upcoming Glamsterdam upgrade splits block building and validation into separate roles, and both builders and validators can deposit ETH. A researcher found that the draft deposit rules could credit a validator's stake to a builder sharing the same public key.

In that scenario, an operator registers as a builder first, then a staking service deposits ETH for a new validator under the same key. Both deposits go to the builder, no validator is created, and the staking service has no proof to recover its funds. Lido, Origin and Rocket Pool were reviewed as potentially exposed, with the findings described as conditional, not confirmed live exploits.

No losses have been reported, and the fix was merged into the consensus specs on Monday, a week after it was first closed for lack of client support.

Under the new rules, pending deposits are sorted by withdrawal credentials, so validator deposits stay with validators. Client teams still need to implement the change. Glamsterdam has already run on Sepolia, but its Oct. 26 launch on the Hoodi testnet was postponed.

Japan's onchain finance push now has the world's largest asset manager on board: BlackRock, SBI Holdings and Startale signed a memorandum of understanding to explore connecting tokenized money market funds with JPYSC, SBI's yen-denominated trust-type stablecoin.

The agreement involves BlackRock Financial Management and BlackRock Japan. The partners will study three areas: technology and infrastructure for connectivity, business models and distribution, and regulatory considerations for tokenized assets and stablecoins.

JPYSC is Japan's first trust-type yen stablecoin, issued under the amended Payment Services Act.

The collaboration is set to be open to other financial institutions in Japan and abroad. The MOU is exploratory and does not yet commit the parties to a specific product or launch date.

Ten months after a conditional nod in December 2025, Ripple has secured final OCC approval to charter Ripple National Trust Bank (RNTB), a federally supervised national trust bank.

RNTB will manage the segregated reserves behind Ripple USD (RLUSD), act as collateral trustee for RLUSD holders and offer fiduciary digital asset custody. RLUSD itself will still be issued by Standard Custody & Trust Company, Ripple's NYDFS-regulated trust company, with BNY as primary reserve custodian.

RLUSD, launched in December 2024, has grown to a $2.5B market cap.

The charter adds federal supervision on top of state oversight for the stablecoin as the U.S. implements the framework set by the GENIUS Act.

Onchain perpetuals have traded worldwide for years, but no registered US exchange or clearinghouse has deployed a market on Hyperliquid. Payward intends to change that, starting with Hyperliquid HIP-3 builder-deployed markets for US clients.

Bitnomial, Payward's CFTC-regulated exchange and clearinghouse, would act as the HIP-3 deployer: it would create, own and administer the markets and clear and settle the contracts. NinjaTrader Clearing, a CFTC-registered futures commission merchant, would carry client accounts, and only allowlisted accounts could trade.

Hyperliquid handled more than $200 billion of volume in the past 30 days, while perpetuals saw over $85 trillion in global trading in 2025.

The contracts would be listed under Bitnomial Exchange rules and remain subject to regulatory approval. Payward says Hyperliquid is the first protocol it plans to deploy on for US clients, with more products to follow.
