Starknet Launches Shadow Accounts to Keep DeFi Wallets Unlinkable

Published October 14, 2026, 07:45 UTC. Based on Starknet's official announcement of October 13, 2026, reporting from Cointelegraph, Crypto Briefing and crypto-economy.com.

Starknet and StarkWare unveiled Shadow Accounts on October 13, a wallet privacy feature that lets users interact with decentralized finance apps through separate, persistent addresses that are not linked on-chain to their main wallets, the project said in its official announcement.

The per-dApp shadow address

Shadow Accounts live inside STRK20, Starknet's privacy framework, according to StarkWare. Each one is a persistent pseudonymous address built for a single application, so a user can keep one identity for lending, another for providing liquidity and a third for trading, with no on-chain thread tying them to each other or to the main address. Users fund the accounts using shielded balances held in the network's STRK20 privacy pool, and a contract called ShadowAccountAnonymizer sits in the middle of the funding flow to cut the connection back to the primary wallet, according to Crypto Briefing. Once a DeFi app integrates the feature, users connect their wallets, switch from public to private mode and deposit assets into a vault, and their Shadow Accounts maintain the positions until they withdraw funds back into a shielded balance, according to Cointelegraph.

What stays public, and what disappears

Shadow Accounts do not hide everything. A shadow account's balances, transactions and positions remain publicly visible on-chain, just like any other address, according to Starknet. The thing that disappears is the link between that account and its owner's main wallet. That narrower approach keeps DeFi's public order books and composability intact while hiding only the connection between accounts. STRK20 also includes a selective disclosure feature aimed at compliance and audit needs, which lets a user open the books to a specific party when required without publishing their entire financial history to everyone else, according to Crypto Briefing. The feature targets wallet address reuse, which lets anyone with a block explorer piece together a user's positions, habits and holdings, exposing users to unwanted tracking and targeted attacks.

The first integrations: Vesu Prime's vSTRK vault, then Ekubo, SuperVega and Opus Money

A demonstration integration with Vesu Prime's vSTRK vault went live on mainnet right after the launch, according to Crypto Briefing, with the first production integration scheduled for October 14, a single day after the unveiling. Rollout is starting across key ecosystem protocols, including Ekubo, SuperVega and Opus Money, according to crypto-economy.com. For builders, integration runs through the Starknet Wallet API version 0.10.4 and starknet.js version 10.8.0, and apps can plug in the feature without being reworked, according to Crypto Briefing. StarkWare said the functionality could eventually extend beyond vaults to liquidity provision, lending, borrowing, staking, derivatives trading, prediction markets and NFT marketplaces, according to Cointelegraph.

StarkWare's privacy roadmap: STRK20, private KYC, and what comes next

Shadow Accounts are a second step rather than a first. StarkWare introduced its STRK20 privacy framework in June 2026, which allows private transfers and shielded token balances on Starknet, according to Cointelegraph. Later that month, the company demonstrated a Private Know Your Customer system that enabled users to verify personal information without revealing their full identity documents. Shadow Accounts take the same idea a step further, from moving money privately to actually using it privately: shielded balances become the funding source for addresses that can go out and interact with DeFi protocols, according to Crypto Briefing. The open questions now are edge-case leakage, whether selective disclosure satisfies auditors and regulators, and whether the roster of integrating protocols grows past the first wave.
