To improve the credit score of your wallet, you would need to take into account our five parameters, i.e., Total asset, Transaction history, Loans ratios, Circulating assets, and Trustworthiness of possessing assets. For instance, you should increase your wallet balance with prestige coins and tokens, perform more transactions and become more active in the crypto market, maintaining good Loan-to-balance and Loan-to-investment ratios, supply more liquidity to lending pools, trade on lending DApps to earn as much profit as you can, avoid collateral liquidation while borrowing, and possess at least $1000 valuable token (e.g., Bitcoin, Ether, or BNB).
