[dynst]

Code like

telescope/packages/telescope/src/helpers/binary-coder.ts

Line 121 in 40a4298

skip(length?: number) {

telescope/packages/telescope/src/helpers/utf8-helper.ts

Line 36 in 40a4298

export function utf8Length(str: string) {

telescope/packages/telescope/src/helpers/binary-coder.ts

Line 437 in 40a4298

uint64 = BinaryWriter.prototype.int64;

is missing explicit types or return types, which breaks
