According to CoinMeta, Defillama and Forgd have introduced a rating system ranging from AAA to CCC, which covers 128 out of 149 listed tokens. Currently, Uniswap holds the sole AAA rating in this system with a comprehensive score of 60.80. This rating system combines information disclosed by the projects with transaction data, and the evaluation criteria include token economics, internal wallets, and business arrangements, among others. Defillama, the head of research at Ryan Celaj, stated that both components of the rating are necessary and one cannot rely solely on the average score. The rating system ranges from 0 to 10, and the final score is multiplied by 10 to produce a result on a 100-point scale. The starting score for the AAA rating is 60, which means that if either component is below 6, it is not possible to achieve the highest rating. Celaj pointed out that the rating thresholds make it difficult to obtain the highest grade, while also creating distinctions between assets with lower ratings.
