Stage 4: Creating VRC-20 Token

To receive rewards, you need a DLP token that meets VRC-20 standards.

📘
Tip
The template with the first VRC-20 implementation is currently under audit and available here: https://github.com/vana-com/vana-smart-contracts/pull/18

🎯 Goal

Launch a DLP token or upgrade an existing one.
Ensure compliance with supply, vesting, and security rules.

Define Token Supply & Emissions

Fixed or Predictable: Decide whether you’ll have a fixed cap or a publicly documented emission schedule. No unlimited mint or rebase.
Team Allocations: Must vest for at least 6 months, then unlock linearly.

Implement Key Contract Requirements

Core ERC-20 Functionality: You can base this on our standard, open-source contract.
Timelocks (48 Hours): Any function that changes fees, minting, or token upgrades must have a 2-day delay.
Transfer Fees ≤3%: If you impose a transaction tax, it can’t exceed 3%.
Liquidity Freedoms: Don’t restrict liquidity providers from adding/removing liquidity in your pool.

Document Your Data Utility

Explain in your readme or whitepaper exactly how your token ties into VRC-15 data usage.
For example: “Users must hold or spend this token to query the dataset,” or “Contributors earn partial rewards in this token.”

Already Have a Token?

Remove or Disable Anything Non-Compliant
- That might be unlimited minting, large rebase logic, or not defined vesting onchain.
- If you used our default DataDAO token contract, you’re automatically compliant as long as no changes are planned. If you plan to make any changes, you’ll need to implement 48-hours timelocks.
Add Vesting Contracts
- If you already distributed some portion to your team, you may need a new lock-up contract or a timelock to ensure 6-month vesting is enforced.
Verify Code
- Ensure your existing main and proxy contracts (if any) are verified on the block explorer.

Final Verification

Deploy your token or finalize your upgrade.
Verify the source code publicly.
Do a quick internal check (or external audit) to confirm each VRC-20 point is satisfied.
The token implementation should pass a Vana Foundation – approved security review (or an equivalent).

📘Tip

If you do not have a token yet, you must launch one in Q2 before Epoch 7 or coordinate with the Vana Foundation to find an alternate approach if you want to be eligible for rewards.
