Turning Custody From a Cost to a Revenue Opportunity

Most asset issuers treat custody as a necessary cost — a fee paid to keep assets safe with no return. Zenrock's Decentralized Custody Tokens (DCTs) change that equation.

DCTs allow issuers to generate yield at the protocol level on BTC, ETH, SOL, and ZEC, turning custody infrastructure from a cost center into a revenue layer.

What Are DCTs?

A DCT is a Zenrock-issued token backed by an underlying asset secured through decentralized multi-party computation (dMPC). Instead of a static custody arrangement, DCTs route custody fees and protocol revenue back to token holders — creating a yield-bearing asset whose returns come from real infrastructure usage.

The yield comes from three sources: custody service fees paid by operators, cross-chain transaction fees generated by asset flows, and fees from offchain financial contracts that use the custodied assets as collateral.

Options for Issuers

When an issuer deploys a DCT, they choose how protocol yield is distributed:

• Pass yield directly to token holders as native BTC, ETH, SOL, or ZEC
• Route yield to a governance treasury for the issuer's protocol
• Retain yield in reserves to strengthen the asset's backing ratio

This flexibility lets issuers design tokenomics that match their protocol's goals rather than accepting a one-size-fits-all arrangement.

What $ROCK Holders Get

$ROCK is the native token of the Zenrock protocol. It captures value from the full DCT ecosystem:

• TVL providers who stake into Zenrock earn a share of custody fees
• DCT issuers create demand for $ROCK by using the network
• $ROCK holders gain economic exposure to every asset flowing through Zenrock's infrastructure

Turning Custody Into a Growth Layer

The traditional model of crypto custody extracts value from asset issuers without returning anything. Zenrock's DCT model inverts this. Custody generates fees, fees fund yield, and yield accrues to holders and the protocol alike.

For BTC, this means native sats paid directly on the Bitcoin blockchain. For ETH and SOL, yield returns in the respective native assets. For ZEC, it opens the first path to productive yield on privacy-preserving digital cash.

By making custody itself a revenue-generating primitive, Zenrock gives issuers a reason to build on decentralized infrastructure rather than simply tolerating it.
