DAY0 DOCUMENTATION

How the complete platform works.

This guide explains the user journey, wallet interactions, contract boundaries, launch process, and risks behind DAY0. It describes the current BSC testnet implementation—not a promise of future returns.

Version 0.2Updated August 2026BSC testnet

Platform overview

DAY0 is a self-custodial DeFi interface. It helps a user prepare and sign transactions, but it never holds private keys or takes custody of wallet assets. The first release focuses on a single BSC market: BNB / DAY0.

01User walletHolds keys and signs
02DAY0 interfaceBuilds safe requests
03V2 routerExecutes swaps/liquidity
04BSCRecords final state
Current safety boundary

The interface is public, but DAY0 has not been deployed and no official liquidity exists. Transaction buttons fail safe until the verified token address is configured.

02

Quick start

  1. 1
    Install or open a Web3 wallet

    Use MetaMask or a compatible mobile wallet. Never share your recovery phrase with DAY0 or any website.

  2. 2
    Connect to DAY0

    Select “Connect wallet.” The wallet reveals only the selected public address.

  3. 3
    Switch to BSC Testnet

    The network button asks the wallet to switch or add the supported test network.

  4. 4
    Use test assets only

    Testnet tokens have no intended monetary value. Never bridge or send real BNB for testing.

  5. 5
    Review every confirmation

    Check the contract, amount, network, and estimated fee in the wallet before signing.

03

Architecture

The platform separates visual presentation, wallet state, chain configuration, and contract calls. This keeps unsupported addresses from silently becoming transaction targets.

Interface layer

Responsive pages for trade, liquidity, earn, portfolio, token, governance, and documentation.

Wallet layer

One shared connection state handles the address, network, and user-approved chain switching.

Configuration layer

Only explicitly configured router, wrapped-native, and DAY0 addresses may be used.

Contract layer

An OpenZeppelin-based fixed-supply ERC-20 plus a compatible V2 liquidity router.

Trading flow

The first supported direction is BNB into DAY0. A swap becomes available only after the router can return a live quote for the configured pair.

  1. 1
    Enter BNB

    The interface converts the amount to 18-decimal base units.

  2. 2
    Request quote

    The router returns the expected DAY0 output for the BNB → WBNB → DAY0 path.

  3. 3
    Apply protection

    DAY0 calculates a minimum output using the 0.5% slippage limit and a 20-minute deadline.

  4. 4
    Sign and settle

    The wallet signs; BSC confirms; output tokens arrive directly at the wallet.

Price impact matters

Slippage protection does not prevent a poor price caused by very low liquidity. Review the output and pool depth before signing.

05

Liquidity flow

Liquidity providers deposit BNB and DAY0 at the current pool ratio. The router returns LP tokens that represent a proportional claim on both reserves and accumulated trading fees.

Adding liquidity

  • 1
    Choose BNB and DAY0 amounts.

    The pool determines the accepted ratio when the transaction executes.

  • 2
    Approve DAY0.

    The ERC-20 approval authorizes the router to transfer only the entered token amount.

  • 3
    Confirm the deposit.

    A second transaction sends BNB and DAY0 into the pair and returns LP tokens.

  • 4
    Track the LP position.

    The portfolio will read the verified LP token after the pair address is deployed and indexed.

Removing liquidity

The holder approves the verified LP token, selects a percentage, and asks the router to return the underlying reserves. Removal stays unavailable until an official pair exists.

06

Earn programs

“Earn” is a registry of verified incentive programs, not an automatic yield promise. A program may become active only when it publishes the reward contract, funding source, reward token, start/end time, withdrawal rules, audit status, and known risks.

No placeholder APR

The interface intentionally shows zero active programs. Displaying invented APR or TVL before contracts exist would misrepresent the protocol.

07

DAY0 token

The token contract has three primary behaviors: transfer, burn, and permit. Its constructor mints exactly 21,000,000 DAY0 to a non-zero treasury address.

Name / symbolDAY0 / DAY0
Maximum supply21,000,000
Decimals18
Additional mintingNot available
BurnHolder-controlled
PermitEIP-2612
UpgradeableNo

The maximum supply can fall when holders burn tokens, but it cannot return to 21 million because no mint function exists.

08

Governance

Governance begins with operational discipline. Before any mainnet deployment, DAY0 needs a multisig with identified signers, a signing threshold, separation of duties, documented treasury rules, and an emergency process. A timelock should protect sensitive administrative actions.

Future community proposals may address incentives, interface defaults, verified asset lists, supported chains, and treasury grants. Governance must not create a hidden mint path or obscure permissions affecting user funds.

09

Security model

Self-custody

Keys remain in the wallet. DAY0 receives only public addresses and signed transaction responses.

Address gates

Missing or malformed addresses keep transaction flows in setup mode.

Transaction limits

Swaps and deposits include slippage minimums and expiration deadlines.

Small token surface

No admin mint, upgrade proxy, blacklist, transfer tax, or pause control is included.

Before mainnet

  • Independent smart-contract and frontend security audits.
  • Verified deployment source and reproducible contract settings.
  • Multisig, timelock, monitoring, alerts, and incident response.
  • Transaction simulation, price-impact warnings, and reliable indexing.
  • Legal review for jurisdictions, token distribution, and user disclosures.

10

Risk disclosure

Market

DAY0 and paired assets can lose value or become illiquid.

Smart contract

Undiscovered flaws in tokens, routers, pairs, or reward contracts can cause loss.

Liquidity

Low reserves increase price impact; LPs face impermanent loss.

Wallet

Compromised keys, malicious approvals, phishing, or signing mistakes can transfer assets.

Governance

Multisig or voting failures can misuse treasury funds or protocol permissions.

Regulatory

Laws and obligations vary and may change across jurisdictions.

No investment assurance

DAY0 documentation explains software behavior. It is not financial, legal, tax, or investment advice.

NEXT REQUIRED DECISION

Create the multisig treasury.

Choose signers, threshold, wallet implementation, operating policy, and recovery process. Do not use a personal wallet as the production treasury.
