THE BLOCK: Charles Schwab has added Solana, Avalanche and Chainlink to its crypto platform, allowing eligible retail clients to buy and sell the three tokens alongside bitcoin and ether. The firm had said in August that solana:So11111111111111111111111111111111111111112, avalanche-2:native and ethereum:0x514910771af9ca656af840dff83e8264ecf986ca would be available "in the coming months." The expansion follows the platform's phased rollout beginning in May and its broader availability to eligible retail clients in October; Schwab charges 75 basis points per transaction and plans to add more digital assets over time.
