Zcash co-founder Sean Bowe submitted an October 2026 proposal to eliminate Zcash Community Grants' automatic 8% share of newly issued ZEC and redirect it to the Network Sustainability Mechanism while leaving the existing treasury intact.

Under its October 2026 proposal, Zcash Community Grants would forgo approximately 62,000 ZEC ($78.5 million) in future allocations and taper its remaining funding through the 2032 Zcash halving, redirecting roughly 98,000 ZEC ($124 million) total to future block rewards.

Under Zcash's block reward distribution rules, 20% of new tokens fund development, with 8% going to Zcash Community Grants and 12% to the Coinholder-Directed Retroactive Grants Program.

The Network Sustainability Mechanism is a Zcash protocol reserve that temporarily removes ZEC tokens from circulation and distributes them to miners as block rewards over decades.

MetaMask added Stellar as part of an initiative to expand its self-custodial financial platform beyond Ethereum-based networks toward its Open Money strategy.

Under TJAR's market structure, applications deposit collected fees into a Token Jar contract, allowing third-party searchers to compete to convert the assets by fulfilling requested target payouts via a Releaser contract.

The Token Jar framework was originally developed to handle Uniswap Protocol fees and processed over $15.3 million in conversions in September 2026.

Uniswap DAO governance retains the authority to introduce an optional protocol fee on TJAR transactions, though no fee is currently activated.

TJAR deployed across seven blockchain networks at launch, with Uniswap Labs publishing developer documentation, contract deployment addresses, and audit reports.

Developers can deploy a Token Jar in a single transaction to configure payment tokens, pricing parameters, and destination addresses, with options to modify or permanently lock settings.

Uniswap trading protocols operate on Robinhood Chain, while Uniswap web app, wallet, and API support Robinhood Stock Tokens.

Liquidity providers on Curve Finance's initial set of Stellar pools can earn trading fees.
