Collector Loans Documentation

Collector Loans is a lending protocol on Solana that lets you borrow USDC against your Pokemon card NFTs from CollectorCrypt — without selling them.

What is Collector Loans?

Collector Loans bridges the gap between collectible card ownership and DeFi liquidity. If you own Pokemon card NFTs through CollectorCrypt, you can use them as collateral to borrow USDC. When you repay your loan within the duration, you get your cards back.

ℹ️ Collector Loans only supports Pokemon cards minted through CollectorCrypt on the Solana blockchain. Physical cards or NFTs from other platforms are not supported.

Key Features

  • Instant Liquidity: Borrow USDC in one atomic transaction, no waiting periods.
  • Keep Your Collection: Your cards are held in escrow, not sold.
  • Three Loan Tiers: Choose Express (2 days), Quick (5 days), or Standard (7 days) — each with its own LTV and flat fee.
  • Flat Fees: No compounding interest. One fixed fee per loan, known upfront.
  • No Liquidation: No margin calls or surprise liquidations. You either repay or forfeit.
  • On-Chain: All transactions are transparent and verifiable on Solana.

Quick Start

Get started with Collector Loans in four steps:

Step 1 — Connect Your Wallet

Click "Launch App" and connect a Solana wallet that holds CollectorCrypt Pokemon card NFTs. We support Phantom, Brave Wallet, and Jupiter.

Step 2 — Select Cards

Your CollectorCrypt cards are detected automatically. Browse them in the Borrow view and select one or more cards to use as collateral.

Step 3 — Choose Your Loan Tier

Pick a tier that fits your needs. Higher LTV gives you more USDC but requires a shorter repayment window and higher fee. The loan summary panel shows exactly what you'll receive and what you'll repay.

Step 4 — Deposit & Borrow

Click "Deposit & Borrow" and approve the transaction in your wallet. Your cards are transferred to escrow and USDC is sent to your wallet in a single atomic transaction.

⚠️ Always verify the transaction details in your wallet before signing. Blockchain transactions are irreversible.

Supported Wallets

Collector Loans supports the following Solana wallets:

Wallet Platform Status
Phantom Browser, iOS, Android Fully supported
Brave Wallet Brave browser (built-in) Fully supported
Jupiter Mobile, Browser extension Fully supported
Ledger Hardware (via Phantom) Supported via Phantom

How Lending Works

Collector Loans uses a collateralized lending model with fixed-duration loans and flat fees. Here's the full lifecycle:

1. Select & Deposit

You select cards from your wallet and choose a loan tier (Express, Quick, or Standard). Your cards are transferred to the Collector Loans escrow wallet, which holds them until the loan is repaid or expires.

2. Receive USDC

Based on your selected tier's LTV ratio and the insured value of your cards, you receive USDC instantly. The deposit and USDC transfer happen in a single atomic Solana transaction — if any step fails, everything reverts.

3. Repay Within Duration

You have a fixed window (2, 5, or 7 days depending on your tier) to repay the loan amount plus the flat fee. Upon repayment, your cards are returned to your wallet in a single transaction.

4. Expiration

If you don't repay within the loan duration, the loan expires and the protocol keeps your cards. There are no additional penalties or debt beyond the collateral.

Loan Tiers

Collector Loans offers three loan tiers. Each tier has a different balance of LTV, duration, and fee:

Tier Duration LTV Flat Fee Best For
Express 2 days 50% 3% Maximum liquidity, quick turnaround
Quick 5 days 40% 2% Balanced terms
Standard 7 days 30% 1.5% Lowest cost, more time to repay

Example

You deposit a card worth 100 USDC:

Express (2 days, 50% LTV, 3% fee)
  You receive:  50.00 USDC
  You repay:    51.50 USDC

Quick (5 days, 40% LTV, 2% fee)
  You receive:  40.00 USDC
  You repay:    40.80 USDC

Standard (7 days, 30% LTV, 1.5% fee)
  You receive:  30.00 USDC
  You repay:    30.45 USDC
ℹ️ The fee is flat — not compounding. You know exactly how much you'll repay the moment you take the loan. The repay amount does not change over the loan duration.

Collateral & Pricing

How Cards Are Valued

Card prices are sourced from CollectorCrypt's metadata API. Each card has an Insured Value assigned by CollectorCrypt based on market data and grading. This is the same valuation used across the CollectorCrypt ecosystem.

Server-Side Verification

When you initiate a borrow, the server fetches the card's insured value directly from CollectorCrypt's API — independent of any data sent by the browser. This prevents price manipulation.

Multiple Cards

You can deposit multiple cards in a single loan. The borrow amount is based on the combined insured value of all deposited cards, multiplied by the selected tier's LTV ratio.

ℹ️ Only cards currently in your wallet can be deposited. Cards already deposited in an active loan are excluded from the borrow view.

Repayment

Repaying your loan returns your cards to your wallet:

  • Go to the Repay tab in the dashboard.
  • Each active loan shows its details, including the repay amount and time remaining.
  • Click "Repay" on the loan you want to close.
  • Approve the transaction in your wallet — you send USDC to the treasury, and your cards are returned in the same transaction.

Repay Amount

The repay amount is fixed at the time of borrowing: borrowed amount x (1 + fee). It does not change over time — no compounding, no surprises.

Partial Repayment

Partial repayment is not supported. You must repay the full amount to retrieve all your cards from a loan.

Deadline

You must repay before the loan expires. The countdown is visible on each loan card in the Repay view. If the loan expires, repayment is no longer possible and the cards are forfeited.

⚠️ Expired loans cannot be repaid. Make sure to repay before the deadline to get your cards back.

Default & Forfeit

If you do not repay within the loan duration:

  • The loan status changes to defaulted.
  • Your deposited cards are kept by the protocol.
  • There is no additional debt, penalty, or collections — the collateral settles the loan.

This model is intentionally simple: you either repay within the window and get your cards back, or you keep the USDC and forfeit the cards. There are no margin calls, no surprise liquidations, and no ongoing debt.

Transactions

All operations in Collector Loans are executed as atomic Solana transactions:

Borrow Transaction

A single transaction that performs two operations atomically:

  • NFT Transfer: Your selected cards are transferred from your wallet to the escrow wallet. For pNFTs (Programmable Non-Fungible Tokens), this uses the Metaplex Token Metadata TransferV1 instruction.
  • USDC Transfer: The treasury sends USDC to your wallet. The treasury partial-signs this instruction server-side.

Repay Transaction

A single transaction that reverses the borrow:

  • USDC Transfer: You send the repay amount (borrowed + fee) to the treasury.
  • NFT Transfer: The treasury sends your cards back to your wallet. The treasury partial-signs these instructions server-side.

Fee Payer

The user pays all Solana network fees (transaction fees, ATA rent). The treasury wallet does not need SOL. Make sure you have a small amount of SOL in your wallet (~0.01 SOL is sufficient for most transactions).

ℹ️ If any part of a transaction fails, the entire operation reverts. You will never lose cards without receiving USDC, or vice versa.

Protocol Addresses

All protocol wallets are publicly verifiable on-chain. Click the Solscan icon to view any address on the explorer.

Wallet Address Purpose
Treasury JCfzjUWEQWsLXmd9izaAXzhdP8wwQgCNptscnxtYPSaK Holds collateral NFTs and lends USDC to borrowers
Fee Wallet J12easbYRRuV1JB8XLJ1Cg4vXkPBBuJrqc1qvNJWtNXQ Receives loan fees on repayment
USDC Mint EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v Official USDC token on Solana (Circle)
ℹ️ When you borrow, the borrowed USDC is sent from the Treasury. When you repay, the principal goes back to the Treasury and the fee goes to the Fee Wallet. All transfers are verifiable on Solscan.

Security

  • Non-Custodial: Collector Loans never has access to your wallet or private keys. All interactions are through signed transactions that you approve in your wallet.
  • Atomic Transactions: Deposits and borrows happen in a single transaction — if any step fails, everything reverts.
  • Server-Side Price Validation: Card prices are verified against the CollectorCrypt API server-side, preventing price manipulation by the client.
  • Wallet Verification: Wallet connections are verified using message signing (Ed25519 signature verification) to prevent spoofing.
  • Protected Keys: The treasury private key is stored outside the web-accessible directory and is never exposed to the browser.

Fees

Fee Type Amount Notes
Express loan fee 3% flat Applied once on the borrowed amount
Quick loan fee 2% flat Applied once on the borrowed amount
Standard loan fee 1.5% flat Applied once on the borrowed amount
Network fee ~0.000005 SOL Standard Solana transaction fee, paid by the user

There are no origination fees, no repayment fees, and no compounding interest. The flat fee is the only cost beyond the Solana network fee.

Frequently Asked Questions

Nothing changes. There are no margin calls or forced liquidations. Your repay amount stays the same regardless of price movement. You either repay within the duration to get your cards back, or you don't.

Only Pokemon card NFTs minted through CollectorCrypt on Solana are supported. Cards from other platforms, physical cards, or non-Pokemon NFTs are not eligible.

It depends on how much USDC you need and how quickly you can repay. Express gives you the most USDC (50% LTV) but you only have 2 days to repay and the fee is 3%. Standard gives less USDC (30% LTV) but you have 7 days and only pay 1.5%. Quick is in the middle.

If the loan expires, the cards are kept by the protocol. There is no additional debt or penalty — the collateral settles the loan. You keep the USDC you borrowed.

No. Each deposit creates a separate loan. To borrow against additional cards, create a new loan.

The user pays all Solana network fees. About 0.01 SOL is enough for most transactions (borrow or repay). If the transaction creates new token accounts, a small additional rent fee may apply.

Yes. The repay amount is set at borrow time and does not change. There is no compounding or daily accrual. If you borrow 50 USDC on the Express tier (3% fee), you repay 51.50 USDC whether you repay after 1 hour or 47 hours.
