Every character on Jiǎoluò Shūwū read as wan in any tone — 2 readings total across the four tones. Pick the tone you mean.
If you have the sound wan but not the character, here are the 2 characters read this way: 完 (wán, to finish; to be whole), 万 (wàn, ten thousand; myriad; all). They split across 2 tones, so the tone is what separates them.
